Configuring IPv6 BGP and IGP route synchronization

By default, upon receiving an IBGP route, an IPv6 BGP router checks the route’s next hop. If the next hop is reachable, the IPv6 BGP router advertises the route to EBGP peers. If the synchronization feature is configured, in addition to the reachability check of the next hop, the IPv6 BGP router must find an active IGP route with the same destination network segment before it can advertise the IBGP route (use the display ipv6 routing-table protocol command to check the IGP route state).

To configure IPv6 BGP and IGP route synchronization:
