Configuring the ASBR-PEs

In the inter-AS IPv6 VPN option C solution, an inter-AS LSP is needed, and the routes advertised between
the PEs and ASBRs must carry MPLS label information. The configuration is the same as that in the

Inter-AS IPv4 VPN option C solution. For more information, see "Configuring MPLS L3VPN."

Configuring the routing policy

A routing policy on an ASBR-PE does the following:

Assigns MPLS labels to routes received from the PEs in the same AS before advertising them to the
peer ASBR-PE.

Assigns new MPLS labels to the labeled routes to be advertised to the PEs in the same AS.

The configuration is the same as that in the Inter-AS IPv4 VPN option C solution. For more information,
see "Configuring MPLS L3VPN."

Displaying and maintaining IPv6 MPLS L3VPN

You can soft-reset or reset BGP sessions to apply new BGP configurations. A soft reset operation updates

BGP routing information without tearing down BGP connections. A reset operation updates BGP routing
information by tearing down, and then reestablishing BGP connections. Soft reset requires that BGP

peers have route refresh capability.
Use the following commands to soft reset or reset BGP sessions:
