3.4.5 Configuring MP-IBGP Between PEs
By importing extended community attributes to BGP, MP-IBGP can advertise VPNv4 routes
between PEs.
Context
Perform the following steps on the PE that is connected to the CE.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp as-number
The BGP view is displayed.
Step 3 Run:
peer ipv4-address as-number as-number
The remote PE is specified as the peer.
Step 4 Run:
peer ipv4-address connect-interface loopback interface-number
The interface used to set up the TCP connection is specified.
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
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.
