Configuring MP-IBGP Between the PE and ASBR in the Same AS

Configuring MP-IBGP Between the PE and ASBR in the Same AS


Perform the following steps on the PE and ASBR in the same AS.


  1. Run system-view

    The system view is displayed.

  2. Run bgp { as-number-plain | as-number-dot }

    The BGP view is displayed.

  3. Run peer ipv4-address as-number as-number-plain

    The peer ASBR is specified as the IBGP peer.

  4. Run peer ipv4-address connect-interface loopback interface-number

    The loopback interface is specified as the outbound interface of the BGP session.


    The 32-bit mask IP addresses of the loopback interfaces must be used to establish the MP-IBGP peer relationship between PEs. This ensures 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.

  5. Run ipv6-family vpnv6 [ unicast ]

    The BGP-VPNv6 address family is displayed.

  6. Run peer ipv4-address enable

    The exchange of VPNv6 routes between the PE and ASBR in the same AS is enabled.


    An ASBR can change the next-hop address of a VPNv6 route to the ASBR's address before advertising the route to a PE.

  7. Run commit

    The configuration is committed.
