Configuring IPv6 BGP and IGP Route Synchronization
With this feature enabled and when a non-BGP router is responsible for forwarding packets in an AS,
IPv6 BGP speakers in the AS cannot advertise routing information to outside ASs unless all routers in
the AS know the latest routing information.
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:
