Configuring a BGP peer group
The peers in a peer group use the same route selection policy.
In a large-scale network, many peers can use the same route selection policy. You can configure a peer
group and add these peers into this group. When you change the policy for the group, the modification
also applies to the peers in the group.
A peer group is an IBGP peer group if peers in it belong to the local AS, and is an EBGP peer group if
peers in it belong to different ASs.
