site to site vpn configuration on cisco router

At the remote site, the import configuration of the VRF instance defines the route-target extended community that is matched and the information that is imported. access-switch1(config-vlan)# name STUDENTS ROUTER2(config-if)# no shut Define a prefix list that matches the default route. The configuration for Layer 2 extension also promotes selective advertisement beyond the BGW. Sub-menu: /ip ipsec Package required: security Internet Protocol Security (IPsec) is a set of protocols defined by the Internet Engineering Task Force (IETF) to secure packet exchange over unprotected IP/IPv6 networks such as Internet. Reachability is Down Table 1 provides the hardware and software requirements for the Cisco Nexus 9000 Series Switches that provide the EVPN Multi-Site BGW function. It thus offers the possibility of seamless extension between compartments and fabrics. Specifies the encryption algorithm used in the IKE policy. Do it all fast and automatically. Model with BGW between spine and superspine. NOTE: As shown above, when reachability is down (i.e destination IP does not respond to ICMP requests), the priority of active router is reduced to 96 and therefore the standby router (ROUTER2) which has priority 100 will become active. In BGP EVPNbased overlay networks, the control plane defines what the data plane and VXLAN use to build adjacencies, for example. To help ensure that endpoints in different IP subnets can communicate without hairpinning through a remote site, knowledge of the /32 and /128 host routes is crucial. Note: The EVPN Multi-Site BGW with VRF-lite coexistence is supported starting NX-OS 7.0(3)I7(3). Lets see an actual configuration below: Configuration. My brother in law who will be living on the other bedroom uses another Notebook (ASUS) just for games and some streaming. In this case, for example, route-target 65501:50000 at the local site can be rewritten as 65036:50000 on the route server and then as 65520:50000 at the remote site. Define the Layer 2 VNI and attach it to a BGW local VLAN. This example uses a local authentication database. crypto map tag client configuration address [initiate | respond]. To monitor the status of our buffer, we can use the show monitor capture buffer command: 2. Explore Catalyst Wireless Gateway Industrial . For details, see the For more information section at the end of this document. Ports 1-2 are assigned to VLAN2 and ports 3-4 to VLAN3, access-switch1(config)# interface range fa 0/1-2 With this approach, and with the existence of an Equal-Cost Multipath (ECMP) network, all BGWs are always equally reachable and active for data-traffic forwarding. The route-target rewrite helps ensure that the ASN portion of the automated route target matches the destination autonomous system. ipsec-isakmp dynamic dynmap, crypto ipsec client Complete these steps in order to set up the site-to-site VPN tunnel via the ASDM wizard: Open the ASDM and navigate to Wizards > VPN Wizards > Site-to-site VPN Wizard: Click Next once you reach the wizard home page: Note: The most recent ASDM versions provide a link to a video that explains this configuration. RTR-B(config-if)# standby 1 track fa0/0. Also enters the Internet Security Association Key and Management Protocol (ISAKMP) group policy configuration mode. Priority 101 (configured 101) In fact, as soon as the first router comes back, this last comes primary again (because it has the higher HSRP priority and the preempt is configured on both ones). During IKE negotiations, the peers search in multiple transform sets for a transform that is the same at both peers. I even know how to plug on the Switch and use a patch panel to make things neat. To provide a safer approach for Layer 2 extension, EVPN Multi-Site architecture allows you to control Layer 2 BUM traffic leaving the local site. The model in which the BGWs are placed between the spine and superspine (Figure 14) is similar to the BGW-to-cloud scenario. Set Up VPN between Cisco ASR 100 Series and Google Cloud Platform Comments. In addition to defining which VLAN or Virtual Routing and Forwarding (VRF) instance is extended, within the Layer 2 extensions you can also control broadcast, unknown unicast, and multicast (BUM) traffic to limit the ripple effect of a failure in one data center fabric. UPDATED: 2020 Cisco Catalyst switches equipped with the Enhanced Multilayer Image (EMI) can work as Layer 3 devices with full routing capabilities.For example, some switch models that support layer 3 routing are the 3550, 3750, 3560 etc. Installing Security Device Manager (SDM) on a Cisco Rou Disabling Cisco Router Password Recovery Service, How To Configure DNS Server On A Cisco Router, Configuring PPTP (VPDN) Server On A Cisco Router. Like the virtual IP address, the PIP address is advertised to the site-internal network as well as to the site-external network. IPsec protocol suite can be divided in following groups: Internet Key Exchange (IKE) protocols. Cisco 4000 Family Integrated Services Routers (ISRs) form an Software Defined WAN platform that delivers the performance, security, and convergence capabilities that todays branch offices need.. Alternative approaches for underlay reachability include the use of IGP, but this document focuses solely on eBGP. HSRP supports different types of tracking, such as interface tracking, routing table tracking, reachability tracking etc. Summary. Group name is hsrp-Et0/0-1 (default), Ethernet0/1 Group 1 For legacy site integration, the BGW is allowed to operate in a vPC domain and to offer the first-hop gateway functions (in this case, DAG). With the route reflector already present in the fabric, and with all VTEPs, including the BGW, peering with it, the exchange of designated-forwarder election messages is achieved (Figure 7). hostname NEWYORK ! With the presence of Layer 2 and the nonhierarchical address space, the large bridged domains have always presented a challenge for scaling and failure isolation. The configuration for a BGW with a site-internal OSPF underlay is shown here. As a result of the external connectivity configuration, you can route to an external domain, preventing the VXLAN BGP EVPN fabric from becoming a transit network and suppressing host-route advertisements. The tracking object 10 above will decrement the priority value of the router by 5 (only if the tracked destination IP 1.1.1.100 is not reachable). With the BGWs between the spine and superspine, data center fabrics are scaled by interconnecting them in a hierarchical fashion. The loopback interface must be present in the same VRF instance on all BGW and with an individual IP address per BGW. Yes, Im the writer of the book you see here (Cisco ASA Firewall Fundamentals). For BUM replication, either multicast (PIM ASM) or ingress replication can be used. Note: The VLAN ID has no significance for any endpoint-facing function. How to configure a Cisco Layer 3 Switch-InterVLAN Routing Without Router, Cisco Switch Port Security Configuration and Best Practices. The supported site-external BUM replication mode is ingress replication. Summary. access-switch1(config-if-range)#switchport mode access Sample route-target prefix and suffix. The E-E-E model uses eBGP-eBGP within the site (fabric) as well as between sites (DCI). Product overview. This is what makes it more difficult to troubleshoot than Serial connections. Preemption enabled enable HSRP group 1 and set the virtual address to 10.10.10.3 In this article we will discuss two different network scenarios where HSRP can be used to provide redundancy between two paths from an internal LAN network towards the outside world (WAN or Internet). The site-external interfaces offer a configuration similar to that for the site-internal interfaces to understand their locations and the need for tracking (evpn multisite dci-tracking). Cisco ASA Site-to-Site IKEv1 IPsec VPN; Cisco ASA Site-to-Site IKEv1 IPsec VPN Dynamic Peer; 90.81.3.157 => ISP router It is important to note that more than one router must be employed at HQ to provide resiliency. If this approach is deemed not beneficial, you can filter external connectivity routes between EVPN Multi-Site fabrics. In addition to the technical details, this document presents design considerations and sample configurations to illustrate the EVPN Multi-Site approach. 86621680: F4CE469A 161C5475 D0612856 tNFTuPa(V86621690: 08004500 00340000 40003406 16F8D056 ..E..4..w.4..xPV866216A0: 9BCBC0A8 03020050 C6BC8F58 11D26100 .K@(PF<.X.Ra.866216B0: C18F8012 39087B6D 00000204 05AC0101 A9. Thus, in the case of two BGWs, you need two prefixes in every BGW: one local to the BGW and one received remotely. The route map is used to select all IP addresses that are attached to an interface and that carry the tag extension. ROUTER1(config-ip-sla)# icmp-echo 1.1.1.100 source-interface Ethernet0/0 However the above scenario is for illustrating the configuration details of HSRP. EVPN Multi-Site architecture allows selective rate limiting for BUM traffic classes that are known to saturate network infrastructure during broadcast storms, loops, and other traffic-generating failure scenarios. Any ideas on what could be happening? These configuration knobs, including the source interface, can be combined in a BGP peer template. Router# config terminal Router(config)# hostname London London(config)# ip domain-name mydomain.com ("Cisco ASA Firewall Fundamentals" and "Cisco VPN Configuration Guide") which are available at Amazon and on this website as well. Specify EVPN Multi-Site interface tracking for the site-internal underlay (evpn multisite fabric-tracking). Local virtual MAC address is 0000.0c07.ac01 (v1 default) Next hello sent in 0.208 secs This capability provides flexibility for existing deployments and transport independence for the site-external network. Verify that the VRF context (IP VRF instance) with the appropriate instance name has been prepared. With the superspine model, all BGWs of all sites connect to all superspines. ROUTER2(config-if)# standby 1 ip 192.168.1.3 Note: The ip pim sparse-mode setting is needed only for intrasite multicast-based BUM replication. A closely related scenario is the case in which the BGW advertises an IP prefix with its own PIP address through local connectivity. This blog is NOT affiliated or endorsed by Cisco Systems Inc. All product names, logos and artwork are copyrights/trademarks of their respective owners. Applying the crypto map to the physical interface instructs the router to evaluate all the traffic against the security associations database. Please provide me the name of your book which also has these. Depending on the VRF awareness and number of VRF instances, this option can be acceptable, but the configuration complexity will increase with the number of VRF instances. In the extended back-to-back topology, with the square plus the full mesh between the BGWs, ECMP is available. Before we dive into the configuration of Cisco EPC, lets explain the two terms used during the EPC configuration: Capture Buffer & Capture Point. See the Cisco IOS Security Command Reference for details. Although this approach doesnt create any problems from a traffic volume or a resiliency perspective, the use of a control-plane exchange between the BGW traversing the leaf node is not natural. Router RTR-A RTR-A(config)# int fa0/1 RTR-A(config-if)# ip address 10.10.10.1 255.255.255.0! EVPN Multi-Site architecture allows the use of multicast (PIM ASM) for BUM replication within one site, while other sites can use ingress replication or multicast. enable HSRP group 1 and set the virtual address to 10.10.10.3 RTR-A(config-if)# standby 1 ip 10.10.10.3! The network will provide a single IP address on the WAN side so that we can configure inbound traffic to reach internal servers (by configuring static NAT for example). This setting allows underlay ECMP reachability from BGW loopback0 to shared-border loopback0. The physical Layer 3 interface for external connectivity must be dedicated and cant be shared with the site-external connectivity for EVPN Multi-Site architecture. Note: You do not need to stop advertising from the site-external underlay because all site-external interfaces are considered to be down. ROUTER2(config-if)# ip address 192.168.1.2 255.255.255.0 enable HSRP group 1 and set the virtual address to 10.10.10.3 RTR-A(config-if)# standby 1 ip 10.10.10.3! There are two tunneling modes available for MX-Z devices configured as a Spoke:. Lets see an actual configuration below: Configuration. Use cases involving Layer 3 extension beyond a single site primarily require multitenant awareness or VPN services. The documentation set for this product strives to use bias-free language. In addition to the EVPN Multi-Site functions, the BGW allows coexistence of VRF-aware connectivity with VRF-lite. {m..,..866216C0: 04020103 030700 . 15:04:51.015 UTC May 25 2015 : IPv4 LES CEF : Fa0 None, 86621680: 5475D061 2856F4CE 469A161C TuPa(VtNF86621690: 08004500 00287443 40007F06 57C0C0A8 ..E..(tC@W@@(866216A0: 0302D056 9BCBC6BC 00506100 C18F8F58 ..PV.KF<.Pa.A..X866216B0: 11D35010 4137B408 00000000 00000000 .SP.A74866216C0: 04. In most cases, the data captured will need to be exported to a network analyzer for additional analysis within a user friendly interface. With selective control-plane advertisement and the enforcement of BUM traffic at the BGWs, you can achieve more control over extension between fabrics. Nothing fancy, but as I told you before, I have no clue how to configure all this, and what kind of equipment should be fine for me. EVPN Multi-Site architecture masks the original advertising VTEP (usually a local leaf node) behind the BGW, and hence the RMAC must match the BGW in between rather than the advertising VTEP. The route target is defined based on the export configuration of the VRF instance in which the prefix was learned. In the rare case in which all DCI-tracking interfaces are down, the BGW performs the following actions: It stops advertising the virtual IP address to the site-internal underlay network. This means that priority will become 101-5=96 which will be lower than the default priority of 100 which is assigned on the standby router (ROUTER2). Client mode is the default configuration and allows only devices at the client site to access resources at the central site. This version is the minimum software release required for EVPN Multi-Site architecture. One such deployment case is described in the Shared border section of this document, and one is described in the Legacy site integration section. RTR-A(config-if)# ip address 10.10.10.1 255.255.255.0, ! Router 1. interface Loopback0 ip address 192.168.1.1 255.255.255.0! The IR829 brings together enterprise-grade wireline-like services such as Quality of Service (QoS), Cisco advanced VPN technologies (DMVPN and Flex VPN) and multi-VRF for WAN, highly secure data, voice, and video communications and Cisco IOx, an open, extensible environment for hosting applications at the network edge. For example: preempt delay min 120 (Wait 2 minutes before coming back primary). The underlay must be reachable between the BGW and the shared border: specifically between the loopback interfaces that provide the VTEP and the overlay peering function. Whatever is sent through the ingress point into the overlay network will leave at the respective egress point. IETF specifications for EVPN Multi-Site architecture, draft-ietf-bess-evpn-prefix-advertisement, Interface-less IP-VRF-to-IP-VRF advertisement, draft-ietf-bess-evpn-inter-subnet-forwarding. The following figure shows the lab for this VPN: FortiGate. IKEv1/IKEv2 Between Cisco IOS and strongSwan Configuration Example Configure a Site-to-Site IPSec IKEv1 Tunnel Between an ASA and a Cisco IOS Router Revision History Defines a transform setan acceptable combination of IPSec security protocols and algorithms. This consistent mapping is called symmetric VNI assignment. When the MP-BGP and VPN address families are used, the route target defines what is imported into a given VRF instance. access-switch1(config-if-range)# exit In addition to using route peering to the external router through eBGP, you may sometimes want to advertise the default route to the fabric. encryption {des | 3des | aes | aes 192 | aes 256}. Configures the router to reply to mode configuration requests from remote clients. The EVPN Multi-Site delay-restore setting is a subconfiguration of the BGW site ID configuration (delay-restore time 300). The Cisco 870 series routers support the creation of Virtual Private Networks (VPNs). vpn1 esp-3des esp-sha-hmac, crypto ipsec rtr-remote local, aaa authorization network Assuming four BGWs and two data center core devices, full-mesh connectivity can be established among them all, using the basic principle of building triangles, not squares. The site-external or DCI interfaces commonly are connected to the network between sites, at which more BGWs are present. Specifies AAA authentication of selected users at login, and specifies the method used. IKEv1/IKEv2 Between Cisco IOS and strongSwan Configuration Example Configure a Site-to-Site IPSec IKEv1 Tunnel Between an ASA and a Cisco IOS Router Revision History The Cisco 870 series routers support the creation of Virtual Private Networks (VPNs). Site-internal and site-external interface status. Now configure a default gateway address of 10.10.10.3 for your LAN hosts. All of the devices used in this document started with a If we included only one ACL statement, then only one-way traffic would be captured. Continuously monitor all file behavior to uncover stealthy attacks. Attach the route filter to the external connectivity peering facing the external router. This article introduced the Cisco Embedded Packet Capture feature offered on all Cisco router IOS platforms from version 12.4.20T and above. Define site-external underlay interfaces facing the external Layer 3 core with the BGW present. The isolated BGW withdraws all of its advertised BGP EVPN routes (Route Type 2, Route Type 3, Route Type 4, and Route Type 5). Specifically, the Designated-Forwarder (DF) function for BUM traffic is distributed on a perLayer 2 VXLAN Network Identifier (VNI) basis. Cisco routers and other broadband devices provide high-performance connections to the Internet, but many applications also require the security of VPN connections which perform a high level of authentication and which encrypt the data between two particular endpoints. This default route is automatically passed through the BGW and advertised to the site-internal VTEPs through BGP EVPN. 4 state changes, last state change 00:01:39 BGW-to-BGW communication is less natural. Multisite bgw-if oper down reason: DCI isolated. The EVPN Multi-Site delay-restore setting is a subconfiguration of the BGW site ID configuration (delay-restore time 300) and applies to both the site-internal and site-external networks. Adjust the MTU setting for the interface to a value that accommodates your environment (the minimum value is 1500 bytes plus VXLAN encapsulation). In my setup, i have two remote systems running on 172.16.0.10 on Side A and 192.168.10.20 on Side B; This tracking object number (10) will be used in the HSRP configuration later. access-switch1(config)#, STEP7: Assign default gateway to the switch, access-switch1(config)# ip default-gateway 10.1.1.254, STEP8: Disable unneeded ports on the switch, ! With this approach, on the control plane, prefixes originating at one site will never be imported back into the same site, thus preventing routing loops. With seamless and controlled Layer 2 and Layer 3 extension through the use of VXLAN BGP EVPN within and between sites, the capabilities of VXLAN BGP EVPN itself have been increased. Configure the peer IP address. The anycast BGW (A-BGW) performs the BGW function as described in the previous section. Ensure the loopback interfaces IP address is redistributed into BGP EVPN, specially towards Site-External. RTR-A(config-if)# standby 1 ip 10.10.10.3, ! To successfully peer with an EVPN Multi-Site BGW, RFC and draft conformity must be achieved, and a common BUM replication mode must be used. Selective advertisement is implicitly enabled. ip prefix-list HOST-ROUTE seq 5 permit 0.0.0.0/0 eq 32. To participate in the designated-forwarder election, the configuration of the same site ID is required. Organizations also have a control point to steer and enforce network extension within and beyond a single data center. Terms of Use and Such a route server can be placed in the Layer 3 cloud or in a separate location reachable from every BGW. Monitor, manage and secure devices description MULTI-SITE INTERFACE (VIP VTEP). For EVPN Multi-Site architecture, BGP EVPN Route Type 4 is used to perform designated-forwarder election. This means that if a destination IP stops responding to ICMP requests, then HSRP will trigger a failover condition and the standby router will take over and start passing traffic. Router# config terminal Router(config)# hostname London London(config)# ip domain-name mydomain.com ("Cisco ASA Firewall Fundamentals" and "Cisco VPN Configuration Guide") which are available at Amazon and on this website as well. With the multitenant capability in BGP EVPN and specifically in EVPN Multi-Site architecture, multiple VRF instances or tenants can be extended beyond a single site using a single control plane (BGP EVPN) and a single data plane (VXLAN). At this point, we have completed the IPSec VPN configuration on the Site 1 router. Test the Site-to-Site connections. Enable the IPv4 unicast address family for this peering. To see all information about the captured packets, use the 'show monitor capture buffer' command: 4. The following commands will configure a Service Level Agreement (SLA) operation which will send ICMP ECHO packets to destination IP 1.1.1.100 from source interface Ethernet0/0 (which is the WAN interface of ROUTER1). configuration address respond, aaa authentication login Active virtual MAC address is 0000.0c07.ac01 With this approach, only after the VRF instance is configured and associated with the VTEP is the relevant IP host and IP subnet prefix information advertised to the site-external network. For cases in which Layer 2 redundancy, for instance, the use of vPC, is required, connectivity to the EVPN Multi-Site BGW is not currently supported. All the per-tenant configuration settings for Layer 3 are provided solely to allow VXLAN traffic termination and reencapsulation for transit through the BGW. The configured rate-limiting level represents the amount of BUM traffic allowed from each interface that faces the site-external network. RTR-B(config-if)# ip address 10.10.10.2 255.255.255.0, ! access-switch1(config-if-range)# switchport access vlan 3 In this article, I will go over deploying a new Routing and Remote Access (RRAS) server and connecting it to an Azure Gateway.The process is not limited to home labs, but it could be also used for a small office environment where a Site-to-Site VPN to RTR-B(config-if)# standby 1 priority 100, ! access-switch1(config)#, STEP6: Assign IP address to the switch for management, !Management IP is assigned to Vlan 1 by default Interface e.g Fast Ethernet0, Dialer0 etc. Any help?? Therefore, every BGW has an active role in BUM forwarding. If one of Lan side layer 2 switch goes down then you will see Active Active situation on both HSRP router. This example uses a local authorization database. Note: The loopback interface used for the EVPN Multi-Site anycast VTEP (virtual IP address) must be advertised to the site-internal underlay as well as to the site-external underlay. To interoperate with a BGW, a site-internal node must support the following functions: VXLAN with Protocol-Independent Multicast (PIM) Any-Source Multicast (ASM) or ingress replication (BGP EVPN Route Type 3) in the underlay, BGP EVPN Route Type 2 and Route Type 5 for the overlay control plane, Route reflector capable of exchanging BGP EVPN Route Type 4, VXLAN Operations, Administration, and Maintenance (OAM)capable devices for end-to-end OAM support. Define a Layer 3 subinterface associated with the previously defined VRF, with a point-to-point subnet and IEEE 802.1q tag (VLAN id). HSRP Ethernet0/0 1 From the BGWs point of view, these externally learned IP prefixes are considered to originate locally from a BGW, using the BGP EVPN address family. This command is mandatory to enable the Multi-Site virtual IP address on the BGW. State is Active Therefore, a VLAN or VRF instance at the local site must be mapped to the same VNI that is used at the remote site. In this case, a dedicated set of border nodes are placed at the site-external portion of multiple sites. interface Tunnel0 ip address 172.16.0.101 255.255.255.0 tunnel source Ethernet0/0 tunnel mode ipsec ipv4 tunnel destination 10.0.0.2 tunnel protection ipsec profile phse2-prof! For a single-autonomous-system deployment, the overlay control-plane configuration is straightforward. Perform these steps to apply a crypto map to an interface, beginning in global configuration mode: Enters the interface configuration mode for the interface to which you want the crypto map applied. When you build networks using the scale-up model, one device or component typically reaches the scale limit before the overall network does. The Cisco Easy VPN client feature can be configured in one of two modesclient mode or network extension mode. The Layer 3 VNI chosen refers to the vn-segment ID chosen in the previous step. Policy Based. Local virtual MAC address is 0000.0c07.ac01 (v1 default) Define the neighbor configuration with the EVPN address family (L2VPN EVPN) for the site-internal overlay control plane facing the route reflector. GRE over IPSEC VPN and OSPF dynamic routing protocol configuration included. Wamique Specifies the IKE pre-shared key for the group policy. It fixes two related security vulnerabilities (CVE-2020-15078) which under very specific circumstances allow tricking a server using delayed authentication (plugin or management) into returning a PUSH_REPLY before the AUTH_FAILED message, which can possibly be used to ip prefix-list DEFAULT-ROUTE seq 5 permit 0.0.0.0/0 le 1. In this article, I will go over deploying a new Routing and Remote Access (RRAS) server and connecting it to an Azure Gateway.The process is not limited to home labs, but it could be also used for a small office environment where a Site-to-Site VPN to If deemed beneficial, separate loopback interfaces can be used for site-internal and site-external purposes as well as for the various routing protocols (router ID, peering, etc.). access-switch1(config-line)# password strongtelnetpass Configuring VXLAN EVPN Multi-Site architecture (Cisco Nexus 9000 Series Switches): https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/vxlan/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x_chapter_01100.html, Configuring VXLAN BGP EVPN (Cisco Nexus 9000 Series Switches): https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/vxlan/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x_chapter_0100.html, VXLAN EVPN configuration example (Cisco Nexus 9000 Series Switches): https://communities.cisco.com/community/technology/datacenter/data-center-networking/blog/2015/05/19/vxlanevpn-configuration-example, Cisco programmable fabric with VXLAN BGP EVPN configuration guide: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/pf/configuration/guide/b-pf-configuration.html, Building hierarchical fabrics with VXLAN EVPN Multi-Site architecture: https://www.cisco.com/c/dam/en/us/products/collateral/switches/nexus-9000-series-switches/at-a-glance-c45-739422.pdf, VXLAN innovations: VXLAN EVPN Multi-Site architecture (part 2 of 2): https://blogs.cisco.com/datacenter/vxlan-innovations-vxlan-evpn-multi-site-part-2-of-2, Design considerations and related references, The magic of superspines and RFC-7938 with overlays: https://learningnetwork.cisco.com/blogs/community_cafe/2017/10/17/the-magic-of-super-spines-and-rfc7938-with-overlays-guest-post, draft-sharma-multi-site-evpn -

EVPN Multi-Site interface tracking is used for the site-external underlay (evpn multisite dci-tracking). debug standby shows this message: Set Up VPN between Cisco ASR 100 Series and Google Cloud Platform. The EVPN Multi-Site BUM enforcement feature can be useful. EVPN Multi-Site architecture allows the extension of Layer 2 and Layer 3 segments beyond a single site. Cisco 5512-X Series ASA that runs software Version 9.4(1) Cisco 1941 Series Integrated Services Router (ISR) that runs Cisco IOS software Version 15.4(3)M2; The information in this document was created from the devices in a specific lab environment. Note: The redistribution from the locally defined interfaces (direct) to BGP is performed through route-map classification. This optimization is achieved by equipping every VTEP with a first-hop gateway and the information needed to take the best path to a given destination. This address will serve as the default gateway address for all hosts on the LAN. I have a Cisco 3750 48 port and also have an HP Proliant server i want to connect to my switch. Model with BGWs between spine and superspine. Perform these steps to configure the Internet Key Exchange (IKE) policy, beginning in global configuration mode: Creates an IKE policy that is used during IKE negotiation. In addition to preventing the VXLAN BGP EVPN fabric from becoming a transit network, you can introduce use another optimization through route filtering. In this article. The good news is, that you can build a Site-to-Site VPN to Azure without having to purchase a VPN appliance. GRE over IPSEC VPN and OSPF dynamic routing protocol configuration included. On a router you will have to configure IP addresses to its interfaces and also a routing protocol (either dynamic routing such as OSPF, EIGRP etc or static routing). With EVPN Multi-Site interface tracking, the BGW function and advertisement and participation are controlled. This setting allows underlay ECMP reachability from BGW loopback0 to route-server loopback0. Failure detection in the site-internal interfaces is one of the main mechanisms offered by EVPN Multi-Site architecture to reduce traffic outages. Note: All BGWs at the same site must have the same site IDs (site ID 1 is shown here). Easy VPN server-enabled devices allow remote routers to act as Easy VPN Remote nodes. If youre tired of setting up SPAN sessions to capture network traffic transiting your network and Cisco router, its time to start using Ciscos Embedded Packet Capture (EPC), available from IOS 12.4.20T and above. This example implements a username of Cisco with an encrypted password of Cisco. Similarly, the route target can be derived automatically by using the BGP autonomous system followed by the VNI defined as part of the VRF instance (ASN:VNI). Copyright 2022 | Privacy Policy | Terms and Conditions | Hire Me | Contact | Amazon Disclaimer | Delivery Policy. Thus, with the use of automated route targets, the configurations of the VRF instance and the route-target extended community potentially diverge. Note: As of Cisco NX-OS 7.0(3)I7(1), automated route-target derivation and route-target rewrite are limited to a 2-byte ASN. Continuously monitor all file behavior to uncover stealthy attacks. access-switch1(config-if-range)# exit, access-switch1(config)# exit preempt allows the router to become the active router when its priority is higher As of Cisco NX-OS 7.0(3)I7(1) for the Cisco Nexus 9000 Series EX- and FX-platform switches, the classification and rate limiting are applied globally to each BGW. In this lab, a small branch office will be securely connected to the enterprise campus over the internet using a broadband DSL connection to demonstrate ASA 5505 site-to-site VPN capabilities. track the WAN interface FE0/0 HSRP: Fa4 Grp 1 Hello Received when interface down. Configure the neighbor in the IPv4 unicast global address family (VRF default) to peer with the site-external loopback interface (loopback0) of the BGW. The BGW with PIP address 10.200.200.21 is local to the show output, and the BGW with PIP address 10.200.200.22 is local to the site and the prefix was received by the BGP EVPN. It also allows different BUM replication modes to be used at different sites. Versatile, reliable, flexible and powerful, the Cisco switch product line (such as the 2960, 3560, 3650, 3850, 4500, 6500, 9400 series etc) offer unparalleled performance and features. This limitation as a result of the route-target format (ASN:VNI) used, which allows space for a 2-byte prefix (ASN) with a 4-byte suffix (VNI). Neither the existing VTEP configuration or the static route-target configuration needs to be changed. This blog entails my own thoughts and ideas, which may not represent the thoughts of Cisco Systems Inc. EVPN Multi-Site architecture introduces external BGP (eBGP) for VXLAN BGP EVPN networks, whereas until now interior BGP (iBGP) was predominant. Now that the tunnel has been established and firewall rules in place, you can try to check whether the connection has been established between the local sites that are set to communicate via the IPSec VPN tunnel. The all-active connection of Layer 4 through Layer 7 (L4-L7) network services (for example, firewalls and load balancers) can be achieved through ECMP routing with a static or dynamic routing protocol. RTR-A(config)# int fa0/1 The simplest scenario is to have all of your Virtual Machines and Laptops in the network range above and assign them IP addresses from the above range (except 192.168.254.254 of course which is already assigned to the default gateway). Test the Site-to-Site connections. By building smaller compartments of fabrics, you improve the individual failure and operation domains. probably of 48 ports, router (not isp provided), lan printer and couple of nodes connected to switch and some Aps. EVPN Multi-Site architecture brings back hierarchies to overlay networks. Note: The ip pim sparse-mode setting is needed only for site-internal multicast-based BUM replication. Our filter is now in place and we are ready for the next step. Every BGW uses its PIP address to perform BUM replication, either in the multicast underlay or when advertising BGP EVPN Route Type 3 (inclusive multicast), used for ingress replication. This capability provides a first-hop gateway for the legacy site and helps ensure seamless endpoint mobility between legacy sites and VXLAN BGP EVPN sites. STEP4: Configure a password for Telnet and Console access. IPSEC VPN configuration lab on Cisco 2811 ISR routers using Cisco Packet Tracer 7.3. Specifies the authentication method used in the IKE policy. Define storm control for EVPN Multi-Site Layer 2 extension. With the implementation of this function, every IETF RFC and draft conforming VTEP can peer with a BGW either site internal or site external without specifically needing to have EVPN Multi-Site BGW capabilities. Commonly, an EVPN Multi-Site deployment consists of two or more sites, which are interconnected through a VXLAN BGP EVPN Layer 2 and Layer 3 overlay (Figure 4). Note: All BGWs at a given site must have the same configurations for Layer 3 extensions. In my opinion, the Cisco switches are the best in the market. Only IP addresses in VRF default that are extended with the matching tag of the route map are redistributed. For VPN resilience, the remote site should be configured with two GRE tunnels, one to the primary HQ VPN router, and the other to the backup HQ VPN router. Router Configuration. As shown, the first 2 translations directed to 74.200.84.4 & 195.170.0.1 are DNS requests from internal host 192.168.0.6.The third entry seems to be an http request to a web server with IP address 64.233.189.99.. With this approach, hierarchies are efficiently used to compartmentalize and interconnect multiple overlay networks. crypto isakmp policy 1 encr aes authentication pre-share group 2 ! Furthermore, you must actively separate the site-internal underlay from the site-external underlay in the E-E-E case, because by default BGP automatically exchanges information between the underlay domains. Network services deployment with EVPN Multi-Site architecture is covered in a separate document. Will the same tutorial apply? Well use figure 1 to help illustrate the terms. This document does not cover the hardware and software requirements for the VXLAN EVPN site-internal network. The two primary topologies discussed here are the BGW-to-cloud model and the model with the BGW between the spine and superspine. The Cisco870 series routers support the creation of Virtual Private Networks (VPNs). The good news is, that you can build a Site-to-Site VPN to Azure without having to purchase a VPN appliance. interface Ethernet0/0 State is Standby Lets now see some verification commands: Ethernet0/0 Group 1 EVPN Multi-Site architecture can also be used for DCI scenarios (Figure 3). Subsequent releases will expand this capability to enable asymmetric VNI assignment, in which different VNIs can be stitched together at the BGW level. The route map enforces the policy to leave the overlay next hop unchanged when the route server is used. The configuration of a shared border to a BGW with an eBGP overlay is shown here. Therefore, the standby router will become active. Supported site-internal BUM replication modes are multicast (PIM ASM) and ingress replication. In cases in which functions such as as-override and allowas-in are used, you must pay special attention to the site-external overlay peering. EVPN Multi-Site technology is based on IETF draft-sharma-multi-site-evpn. The route server must be able to support the EVPN address family, reflect VPN routes, and manipulate the next-hop behavior (next-hop unchanged). Virtual IP address is 1.1.1.3 Have a great day. All of the devices used in this document started with a The new network topology models build well-designed hierarchical networks, but with the addition of VXLAN as an over-the-top network this hierarchy was being flattened out. Note: Every BGW will have an active designated-forwarder role if the number of Layer 2 VNIs exceeds the number of BGWs. In my opinion, the Cisco switches are the best in the market. Privacy Policy. Activate the IPv4 unicast global address family (VRF default) to redistribute the required loopback and, if needed, the IP addresses of the physical interfaces within BGP. However, for an EVPN Multi-Site BGW, no endpoint-facing Layer 2 or Layer 3 configuration is defined. Ron, yes the tutorial will apply to your case as well. Monitor, manage and secure devices Here we have a network setup which is very useful in enterprises for providing ISP redundancy. The BGW is the binding device between the site-internal VTEPs and everything that is site external. In VXLAN EVPN, Cisco NX-OS uses an automated route-target derivation in which a prefix is followed by a 2-byte Autonomous System Number (ASN). The VRF-lite coexistence model (Figure 20) uses the traditional approach to providing external connectivity to a VXLAN BGP EVPN fabric. For configuration guidance for dual- and multiple-autonomous-system designs, see the For more information section at the end of this document. In addition to per-BGW or per-site external connectivity, connectivity can be provided through a shared border. The designated-forwarder assignment is performed on a perLayer 2 VNI basis, using a round-robin process to distribute assignments equally. The EVPN Multi-Site fabric-tracking function detects whether one or all of the site-internal interfaces are available. Prevent breaches. Control-plane advertisements are limited based on the local VRF and VNI configurations on the BGWs. Enable feature bgp for underlay IPv4 unicast routing. All of the devices used in this document started with a cleared (default) configuration. Note: The default route should be advertised only to the site-internal VTEPs. Migrating ASA to Firepower Threat Defense Site-to-Site VPN Using IKEv2 with Certificates AnyConnect HostScan Migration 4.3.x to 4.6.x and Later 29-Aug-2019 Cisco ASA REST API Quick Start Guide 05-Jun-2019 Full set of commands and diagrams included. Define a VRF context (IP VRF) with the appropriate instance name. Full set of commands and diagrams included. The back-to-back connectivity model (Figure 11) provides an alternative to the topology in which the BGWs are connected to a Layer 3 cloud. Define a route map that matches the prefix list, and prevent that match from being advertised to the external connectivity. Ensure the loopback interfaces IP address is redistributed into BGP EVPN, specially towards Site-External. Specifies the peer IP address or hostname for the VPN connection. Note: The VLAN ID and point-to-point subnet must match the neighboring interface. Activate the IPv4 unicast global address family (VRF default) to redistribute the required loopback and physical interface IP addresses within BGP. Hello, you didnt tell us what kind of ISP connection you have and also what kind of ISP equipment (WiFi router etc?). You could also use a RADIUS server for this. As of Cisco NX-OS 7.0(3)I7(1) for the Cisco Nexus 9000 Series EX- and FX-platform switches, all deployed sites must follow a consistent assignment of VNIs for either Layer 2 or Layer 3 extension. On a Layer3-capable switch, the port interfaces work as Layer 2 access ports by default, but you can also configure them as Routed Tunneling. Creates source proxy information for the crypto map entry. Following the introduction of eBGP next-hop behavior, Autonomous Systems (ASs) at the Border Gateways (BGWs) were introduced, returning network control points to the overlay network. crypto isakmp key 0 address 172.16.1.1 ! The previous topologies used dedicated BGW nodes. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. This example assumes a symmetric VNI deployment (the same VNI across sites). This document uses the virtual IP address to refer also to the EVPN Multi-Site anycast IP address. You might need to buy 1-2 wifi access points as well in order to extend the wifi network coverage. please help. In addition to the show commands presented in this section, VXLAN OAM (NGOAM) works consistently for single-site and EVPN Multi-Site architecture. multisite border-gateway interface loopback100. VXLAN was supposed to address this challenge, but it has increased the challenge, with even larger Layer 2 domains being built as the location boundary was overcome by the capability of VXLAN to provide Layer 2 over Layer 3 networking. Note: Without the route filter, the VXLAN BGP EVPN fabric can accidentally become a transit network for traffic external to the fabric. access-switch1(config)#, STEP9: Configure Layer2 VLANs and assign ports to the them. 30.30.30.20 30.30.30.30, crypto map dynmap isakmp Remote access VPNs are used by remote clients to log in to a corporate network. First create the Layer2 VLANs on the switch, access-switch1(config)# vlan 2 The per-neighbor configuration for the overlay control-plane function in a route server can be simplified. Define the OSPF process tag and OSPF router ID. Unlike serial connections the Ethernet WAN interface could be in an up/up condition and in fact be down. R2 is not becoming part of that standby 1 group. access-switch1(config-std-nacl)# permit 10.1.1.101 All the use cases for EVPN Multi-Site architecture have the name space provided by VXLANthe VXLAN network identifier, or VNIas a central feature. Note: EVPN Multi-Site architecture uses VXLAN encapsulation for the data plane, which requires 50 or 54 bytes of overhead on top of the standard Ethernet MTU (1550 or 1554). set transform-set transform-set-name [transform-set-name2transform-set-name6]. Assuming two BGWs per site, the back-to-back connectivity model builds a square between the two BGWs at the local site and the two BGWs at the remote site. VXLAN EVPN Multi-Site architecture provides integrated interconnectivity that doesnt require additional technology for Layer 2 and Layer 3 extension. thank you so much. EVPN Multi-Site architecture provides additional status information about the BGW VTEP. Define the loopback1 interface as the NVE source interface (PIP VTEP). The Layer 3 underlay between all BGWs is achieved with a point-to-point subnet and the advertisement of the virtual IP and PIP addresses of the BGWs into this routing domain. Ethernet links do not have the end-to-end keep-alive or clock mechanisms of serial links thus it is more difficult to identify when a link is down end-to-end. As long as one of these interfaces is operational and available, the BGW can extend Layer 2 and Layer 3 traffic to remote sites. BGW21-N93180EX# show nve multisite dci-links, Multisite bgw-if: loopback100 (ip: 10.111.111.1, admin: Up, oper: Down). All of these sites connect through VXLAN BGP EVPN to this shared border set, which then provides external connectivity. This section explores the configurations needed for the VNIs, for either Layer 2 or Layer 3 extension. BGW21-N93180EX# show nve interface nve 1 detail, Interface: nve1, State: Up, encapsulation: VXLAN, VPC Capability: VPC-VIP-Only [not-notified], Source-Interface: loopback1 (primary: 10.200.200.21, secondary: 0.0.0.0), Multi-Site delay-restore time: 180 seconds, Multi-Site delay-restore time left: 0 seconds, Multisite bgw-if: loopback100 (ip: 10.111.111.1, admin: Up, oper: Up), Nve MultiSite Src node last notif sent: Port-up. Specifies AAA authorization of all network-related service requests, including PPP, and specifies the method of authorization. Standby router is 1.1.1.2, priority 100 (expires in 10.048 sec) Cisco routers and other broadband devices provide high-performance connections to the Internet, but many applications also require the security of VPN connections which perform a high level of authentication and which encrypt the data between two particular endpoints. From an intersite underlay, eBGP can be replaced with any routing protocol, as long as a clean separation exists between the site-internal and site-external routing domains. Cisco Router 851 871 Interfaces and Basic Configuration Guide Setup, Configuring EasyVPN Between Cisco Routers, Standby router is 1.1.1.2, priority 100 (expires in 10.048 sec), Standby router is 192.168.1.2, priority 100 (expires in 9.728 sec), Active router is 1.1.1.2, priority 100 (expires in 10.848 sec), Active router is 192.168.1.2, priority 100 (expires in 8.176 sec). Your email address will not be published. In this article. Note: All BGWs for a given site must have the same configuration for Layer 2 extensions. The autonomous system portion of the automated route target (ASN:VNI) will be rewritten upon receipt from the site-external network (rewrite-evpn-rt-asn) without modification of any configuration on the site-internal VTEPs.
