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
The BGP VPNv4 sub-address family view is displayed.
Step 6 Run:
peer ipv4-address enable
The VPN IPv4 routing information can be exchanged between the peers.
