Configuring the Route Reflectors to Exchange VPN-IPv4 Routes
This example shows how to configure the route reflectors to exchange VPN-IPv4 routes by using multihop.
This task specifies that the next-hop information and the VPN label are to be preserved across the autonomous
system (AS).
Configuration Example
Router# configure
Router(config)# router bgp 500
Router(config-bgp)# neighbor 10.200.2.1
Router(config-bgp-nbr)# remote-as 100
Router(config-bgp-nbr)# ebgp-multihop
Router(config-bgp-nbr)# update-source loopback0
Router(config-bgp-nbr)# address-family vpnv4 unicast
Router(config-bgp-nbr-af)# route-policy pass-all in
Router(config-bgp-nbr-af)# route-policy pass-all out
Router(config-bgp-nbr-af)# next-hop-unchanged
Router(config-bgp-nbr)# address-family vpnv6 unicast
Router(config-bgp-nbr-af)# route-policy pass-all in
Router(config-bgp-nbr-af)# route-policy pass-all out
Router(config-bgp-nbr-af)# next-hop-unchanged
