Enabling EVPN VXLAN Layer 3 TRM Interworking with MVPN Networks To configure interworking of Layer 3 TRM with MVPN networks, perform the following steps: Configuring EVPN VXLAN External Connectivity Enabling EVPN VXLAN Layer 3 TRM Interworking with MVPN Networks Command or Action Purpose Step 25 import l2vpn evpn re-originate Example: Device(config-router-af)# import l2vpn evpn re-originate Reoriginates the EVPN routes imported from the EVPN fabric into the VPNv6 address family as VPNv6 routes and distributes them to the external network. Step 26 neighbor ip-address activate Example:
Device(config-router-af)# neighbor 172.16.255.103 activate Enables the exchange information from a BGP neighbor. Use the IP address of the spine switch as the neighbor IP address. Step 27 neighbor ip-address send-community [both | extended | standard] Example: Device(config-router-af)# neighbor 172.16.255.103 send-community both Specifies the communities attribute sent to a BGP neighbor. Use the IP address of the spine switch as the neighbor IP address. Note Use either of extended or both keywords. External connectivity cannot be established when you use the standard keyword. Step 28 neighbor {ip-address | peer-group-name} next-hop-self [ all] Example:
Device(config-router-af)# neighbor ip-address next-hop-self all Configures the router as the next hop for a BGP-speaking neighbor or peer group. The all keyword is mandatory when implementing external connectivity through iBGP, where the EVPN fabric and the MPLS network are in the same BGP autonomous system number. The all keyword is optional when implementing external connectivity through eBGP, where the EVPN fabric and the MPLS network are in different BGP autonomous system numbers. Step 29 exit-address-family Example: Device(config-router-af)# exit-address-family Exits address family configuration mode and returns to router configuration mode. Step 30 end Example:
Device(config-router)# end Returns to privileged EXEC mode. Configuring EVPN VXLAN External Connectivity 15
