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 to verify that the next hop of the OSPFv3
route to the peer CE is the VLAN interface connected to the PE. The VPN traffic to the peer is forwarded
over the backbone. (Details not shown.)
# Verify that a sham link has been established on PEs, for example, on PE 1.
