Configuring Route Dampening; Configuring Ipv6 Bgp Route Attributes; Prerequisites; Configuring Ipv6 Bgp Preference And Default Local_Pref And Next_Hop Attributes - 3Com S7906E Configuration Manual

By default, when a BGP router receives an iBGP route, it only checks the reachability of the route's next
hop before advertisement. If the synchronization feature is configured, only the iBGP route is advertised
by IGP can the route be advertised to eBGP peers.
Follow these steps to configure IPv6 BGP and IGP route synchronization:
Enter system view
Enter BGP view
Enter IPv6 address family view
Enable route synchronization between
IPv6 BGP and IGP
