VPNv4 routes by route targets.
The routes surviving the filtering

Configuring inter-AS option C
To configure inter-AS option C, perform configurations on PEs and ASBR PEs, and configure routing
policies on the ASBR PEs.
Configuring a PE
Establish an ordinary IBGP peer relationship between a PE and an ASBR PE in an AS, and an MP-EBGP
peer relationship between PEs of different ASs.
The PEs and ASBR PEs in an AS must be able to exchange labeled IPv4 routes.

1. Enter system view. system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Configure the ASBR PE in the
same AS as an IBGP peer.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer is created.
4. Configure the PE of another
AS as an EBGP peer.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer is created.
5. Enter BGP IPv4 unicast
address family view.

6. Enable the PE to exchange
IPv4 unicast routes with the
peer or peer group.
peer { group-name | ip-address }

By default, BGP does not exchange
IPv4 unicast routes with any peer.
7. Enable the PE to exchange
labeled IPv4 routes with the
ASBR PE in the same AS.
peer { group-name | ip-address }
