Network requirements
As shown in
PE 1 and PE 2 so traffic between the CEs is forwarded through the MPLS backbone instead of the
backdoor link.

Configuration procedure
1. Configure OSPFv3 on the customer networks:
# Configure conventional OSPFv3 on CE 1, Router A, and CE 2 to advertise addresses of the
interfaces (see
# Set the cost value to 2 for both the link between CE 1 and Router A, and the link between CE
2 and Router A. (Details not shown.)
# Execute the display ipv6 routing-table command to verify that CE 1 and CE 2 have learned
the route to each other. (Details not shown.)
2. Configure IPv6 MPLS L3VPN on the backbone:
# Configure basic MPLS and MPLS LDP on PE 1 to establish LDP LSPs.
