A neighbor may keep its configuration after it was added to a peer group if the neighbor’s
configuration is more specific than the peer group’s, and the neighbor’s configuration does not
affect outgoing updates.
A peer group must exist before you add a peer to it. If the peer group is disabled (shutdown)
the peers within the group are also disabled (shutdown).
