Establishing an MP-EBGP Peer Relationship Between Each AGG and MASG

Procedure

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 | as-number-dot }

   A BGP peer is configured.

4. Run peer { ipv4-address | group-name } connect-interface loopback interface-number

   The interface on which a TCP connection to the specified BGP peer is established is specified.

   

   The AGG and MASG must use loopback interface addresses with 32-bit masks to establish an MP-EBGP peer relationship so that the MP-EBGP connection can recurse to a tunnel.

5. Run peer ipv4-address ebgp-max-hop [ hop-count ]

   The maximum number of hops for an EBGP peer relationship is set.

6. Run ipv4-family vpnv4

   The BGP-VPNv4 address family view is displayed.

7. Run peer { ipv4-address | group-name } enable

   The ability to exchange BGP-VPNv4 routes with the specified BGP peer is enabled.

8. (Optional) Run ipv4-family unicast

   The BGP-IPv4 unicast address family view is displayed.

9. (Optional) Run undo peer { ipv4-address | group-name } enable

   The ability to exchange BGP-VPNv4 unicast routes between BGP peers is disabled.

   If multiple links between two ASs exist, the ability to exchange BGP-VPNv4 unicast routes between BGP peers must be disabled to prevent route loops between BGP peers that establish MP-EBGP peer relationships.

10. Run commit

    The configuration is committed.
