The BGP view is displayed.
Step 3 Run:
peer ipv4-address as-number as-number
The peer ASBR is specified as the IBGP peer.
Step 4 Run:
peer ipv4-address connect-interface loopback interface-number
The loopback interface is specified as the outgoing interface of the BGP session.
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 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 PE and ASBR in the same AS is enabled.
