Verifying the configuration
# Execute the display ipv6 routing-table vpn-instance command on the PEs to verify the following
results (details not shown):
•
The path to the peer CE is now along the IPv6 BGP route across the backbone.
•
A route to the sham link destination address exists.
# Execute the display ipv6 routing-table command on the CEs. Verify that the next hop of the
OSPFv3 route to the peer CE is the interface connected to the PE (VLAN-interface 11). This means
that the VPN traffic to the peer CE is forwarded over the backbone. (Details not shown.)
# Verify that a sham link has been established on PEs, for example, on PE 1.
