Configuring IPv6 MBGP route summarization
To reduce the routing table size on medium and large BGP networks, you must configure route
summarization on IPv6 MBGP routers. BGP supports only manual summarization of IPv6 multicast
routes.
To configure IPv6 MBGP route summarization:

[

Not advertised by default.
NOTE:
With the
peer
default-route-advertise
command executed, the router sends a default route with the
next hop as itself to the specified IPv6 MBGP peer or the specified peer group, regardless of
whether the default route is available in the routing table.
Configuring outbound IPv6 MBGP route filtering
Members of an IPv6 MBGP peer group must have the same outbound route filtering policy as the
peer group.
IPv6 BGP advertises redistributed routes that pass the specified policy to the IPv6 MBGP peer.
