Displayed 3 routes and 3 total paths
According to RFC 5065:the usage of one of the member AS number as the
confederation identifier is not forbidden.
fixes are the following
in bgp_route.c:
in bgp_update remove the test for presence of confederation id in
as_path since, this case is allowed;
in bgp_vty.c
bgp_confederation_peers, remove the test on peer as value
in bgpd.c
bgp_confederation_peers_add
remove the test on peer as value
invert the order of setting peer->sort value and peer->local_as,
since peer->sort is depending from current peer->local_as value
bgp_confederation_peers_remove
invert the order of setting peer->sort value and peer->local_as,
since peer->sort is depending from current peer->local_as value
