Deployment Guide

10. Configure a Loopback interface for BGP EVPN peering different from VLT peer IP address
OS10(config)# interface loopback1
OS10(conf-if-lo-1)# no shutdown
OS10(conf-if-lo-1)# ip address 172.18.0.1/32
OS10(conf-if-lo-1)# exit
11. Configure BGP EVPN peering
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# neighbor 172.201.0.1
OS10(config-router-neighbor)# remote-as 101
OS10(config-router-neighbor)# ebgp-multihop 4
OS10(config-router-neighbor)# send-community extended
OS10(config-router-neighbor)# update-source loopback1
OS10(config-router-neighbor)# no shutdown
OS10(config-router-neighbor)# address-family ipv4 unicast
OS10(config-router-bgp-neighbor-af)# no activate
OS10(config-router-bgp-neighbor-af)# exit
OS10(config-router-neighbor)# address-family l2vpn evpn
OS10(config-router-bgp-neighbor-af)# activate
OS10(config-router-bgp-neighbor-af)# allowas-in 1
OS10(config-router-bgp-neighbor-af)# exit
OS10(config-router-neighbor)# exit
OS10(config-router-bgp-100)# neighbor 172.202.0.1
OS10(config-router-neighbor)# remote-as 101
OS10(config-router-neighbor)# ebgp-multihop 4
OS10(config-router-neighbor)# send-community extended
OS10(config-router-neighbor)# update-source loopback1
OS10(config-router-neighbor)# no shutdown
OS10(config-router-neighbor)# address-family ipv4 unicast
OS10(config-router-bgp-neighbor-af)# no activate
OS10(config-router-bgp-neighbor-af)# exit
OS10(config-router-neighbor)# address-family l2vpn evpn
OS10(config-router-bgp-neighbor-af)# activate
OS10(config-router-bgp-neighbor-af)# allowas-in 1
OS10(config-router-bgp-neighbor-af)# exit
OS10(config-router-neighbor)# exit
OS10(config-router-bgp-100)# exit
12. Configure EVPN for the VXLAN virtual network
Configure the EVPN instance in manual configuration mode, and RD and RT configuration in auto mode.
OS10(config)# evpn
OS10(config-evpn)# evi 20000
OS10(config-evpn-evi-20000)# vni 20000
OS10(config-evpn-evi-20000)# rd auto
OS10(config-evpn-evi-20000)# route-target auto
OS10(config-evpn-evi-20000)# exit
OS10(config-evpn)# exit
13. Configure VLT
Configure a VLTi VLAN for the virtual network
OS10(config)# virtual-network 20000
OS10(config-vn-20000)# vlti-vlan 200
OS10(config-vn-20000)# exit
Configure a dedicated L3 underlay path to reach the VLT Peer in case of a network failure
OS10(config)# interface vlan4000
OS10(config-if-vl-4000)# no shutdown
OS10(config-if-vl-4000)# ip address 172.16.250.10/31
OS10(config-if-vl-4000)# exit
