   3 Subject: [bgp/pgbgp] Add some pgbgp commands to restricted-mode and other command tweaks
   4 X-Git-Url: http://git.ozo.com/?p=quagga-pgbg.git;a=commitdiff_plain;h=06ac72f9f6021635e9e1e5105c3e22bf7eb0d6c3
   5
   6 [bgp/pgbgp] Add some pgbgp commands to restricted-mode and other command tweaks
   7
   8 * bgp_pgbgp.c:
   9   (edge_neighbor_iterator) make ASN==0 mean 'iterate over all ASNs'
  10   (bgp_pgbgp_stats_origin_one) new function, to display one origin AS status.
  11   (bgp_pgbgp_stats_origins) adapt to use previous.
  12   Adapt to iterate over all stats if no prefix was giving.
  13   (show_ip_bgp_pgbgp_neighbors_cmd) recognise no ASN argument case
  14   (show_ip_bgp_pgbgp_neighbors_all_cmd) Iterate over all
  15   (show_ip_bgp_pgbgp_origins_cmd) similar
  16   (show_ip_bgp_pgbgp_origins_all_cmd)
  17   (bgp_pgbgp_enable) install the lookup commands to ther new RESTRICTED_NODE
  18 * bgp_route.c:
  19   (route_vty_short_status_out) only allowed to print one char for anomalous
  20   status.
  21   (route_vty_out_detail) Add support for printing out more detail on
  22   PG-BGP status
