Configuration Guide
I. Creating a peer group with members
By default, an IBGP peer will be added to a default peer group without configuration.
Such default group is invisible. The configuration of the route updating policy on any
IBGP peer is valid for the other group members only. If the router is not a route reflector,
all the IBGP peers stay belong to a same group. Otherwise, all the route reflection
clients belong to one group, and others to another.
EBGP peer group members must be in a same network segment. Otherwise, the route
updating packets sent from a router might be discarded by some EBGP peers.
IBGP peer and EBGP peer cannot be added into one group.
