be established first and be configured. Then add all the peers to the peer group so
that they have the same configuration as this peer group.
The default IBGP peer will be added to the default peer group without any
configuration. The configuration of the route update policy for any IBGP peer is
valid for the other IBGP peers in its group. To be specific, if the router is not a
route reflector, all the IBGP peers are in the same group. If the router is a route
reflector, all the route reflection clients are in a group, while non-clients are in
another group.
The external peer group members must be in the same network segment.
Otherwise, some EBGP peers may discard the transmitted route update.
The peer group members cannot be configured with the route update policy
which is different from that of the peer group, but can be configured with
different ingress policies.
Example
Establish a peer group "test".
