Prefix lists are yet another way of implementing BGP policy. A Prefix List
enables filtering of route advertisements based on IP prefixes.
This is a group of BGP neighbors that share update policies. Instead of
defining the same policies for several individual peers, a peer group is defined
and policies are assigned to the group. That way, the operator is saved from
repetitive configuration. It also reduces the load on system resources by
allowing the routing table to be checked only once, and updates to be
replicated to all peer group members instead of formulating updates
individually for each peer in the peer group.
Multi-protocol BGP(MBGP) can be used to carry routing information for the
IPv6 address family. All BGP commands and routing policy capabilities can
be used with IPv6 addresses. Other address families(like IPv4 multicast, IPv6
multicast) will not be supported as part of MBGP.
