advertise labeled routes to any
IPv4 peer/peer group.

Enable the PE to exchange
BGP VPNv6 routing
information with the EBGP
peer.

By default, the PE does not
exchange labeled routes with any
IPv4 peer/peer group.
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 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 an OSPFv3 sham link
Before you configure an OSPFv3 sham link, configure basic IPv6 MPLS L3VPN (OSPFv3 is used between
PE and CE).
