IPv6 BGP advertises routes passing the specified policy to peers. Using the
protocol
argument can filter
only the routes redistributed from the specified protocol. If no
protocol
is specified, IPv6 BGP filters all
routes to be advertised, including redistributed routes and routes imported with the
network
command.

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.
