Configuring an OSPFv3 sham link
Network requirements
As shown in Figure 96 , CE 1 and CE 2 belong to VPN 1. Configure an OSPFv3 sham link between
PE 1 and PE 2 so traffic between CE 1 and CE 2 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 as shown in
Figure 96 . 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. Execute the display ipv6 routing-table
command to verify that CE 1 and CE 2 have each learned the OSPFv3 route to the
GigabitEthernet interface of the 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.
