Parameters
group-name: Specifies a name for the peer group, a case-sensitive string of 1 to 47 characters.
external: Creates an EBGP peer group.
internal: Creates an IBGP peer group.
Usage guidelines
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. In this way, peers can share the same policy as the peer
group. When the policy of the group is modified, the modification also applies to peers in it.
If the internal or external keyword is not specified, the command creates an IBGP peer group.
If you perform configurations on a peer group and peers of the peer group, the last configuration takes
effect.
After you create a peer group, you must use the peer enable command to enable BGP to exchange
routing information with the specified peer group.
