[bgpd] Add RIB reporting commands, show bgp ... statistics
2006-09-13 Paul Jakma <paul.jakma@sun.com>
* bgp_aspath.c: (aspath_highest) new, return highest ASN in an
aspath.
* bgp_route.c: (bgp_peer_count_walker) new, do the walk done
in bgp_peer_counts as a thread.
(bgp_peer_counts) move walk to previous and call it via
thread_execute so this RIB walk shows up in thread stats.
(bgp_table_stats) New, gather some statistics for a given
RIB.
(bgp_table_stats_walker) New, RIB walker thread for former.
(bgp_table_stats_vty) Parsing front-end for 'show bgp ...',
useful model for future rationalisation of 'show ... bgp'.
(bgp_route_init) Add new RIB stats commands.
