Huawei AR1200 Series Configuration Guide

NOTE
The 32-bit mask IP addresses of the loopback interfaces must be used to establish the MP-IBGP peer
relationship between PEs. This can ensure that the tunnel can be iterated. The route destined to the loopback
interface is advertised to the remote PE based on IGP on the MPLS backbone network.
Step 5 Run:
ipv4-family vpnv4 [ unicast ]
The BGP-VPNv4 address family is displayed.
Step 6 Run:
peer ipv4-address enable
The exchange of IPv4 VPN routes between the PE and ASBR in the same AS is enabled.
NOTE
In the AR1200, an ASBR can only change the next-hop address of a VPNv4 route to the ASBR's address
before advertising the route to a PE.
