pybird - BIRD interface handler for Python

PyBird is a Python interface to the BIRD Internet Routing Daemon's UNIX control socket, handling the socket connections and parsing the output.

In it's current state, you can use it to query the status of specific or all BGP peers, to query the routes received, accepted and rejected from a peer, or the general status of BIRD (router ID, last config change)

Usage example

>>> from pybird import PyBird
>>> pybird = PyBird(socket_file='/var/run/bird.ctl')
>>> peer_state = pybird.get_peer_status('KPN')
>>> peer_state['up']
True
>>> peer_state['import_updates_received']
4214
>>> peer_state['last_change']
datetime.datetime(2011, 6, 19, 19, 57, 0, 0)
>>> rejected = pybird.get_peer_prefixes_rejected('KPN')
>>> rejected[0]['as_path']
'23456 65592'
>>> status = pybird.get_status()
>>> status['last_reconfiguration_time']
datetime.datetime(2012, 1, 3, 12, 46, 40)
>>> status['router_id']
"192.168.0.1"

You can also call get_peer_status() without a peer name, to get an array with all the BGP peers.

Full field list for peers

All fields that are decoded, if present:

  • name: Name as configured in BIRD
  • protocol: Currently always "BGP"
  • last_change: Last state change as a datetime.datetime object
  • state: String of the peer status, e.g. "Established" or "Passive"
  • up: Boolean, True if session is Established
  • routes_imported: Number of imported routes
  • routes_exported: Number of exported routes
  • router_id: BGP router id

And all combinations of: [import,export]_[updates,withdraws]_[received,rejected,filtered,ignored,accepted] which BIRD supports.

Full field list for routes

All fields that are decoded, if present:

  • origin: BGP origin, e.g. "IGP"
  • as_path: AS path as string
  • next_hop: BGP next hop
  • local_pref: Local pref, e.g. '100'
  • community: Communities in BIRD string format, e.g. '(8954,620)'

And any other BGP attribute fields BIRD has found.

Full field list for BIRD status

  • router_id: BGP Router ID as string
  • last_reboot: Last BIRD restart time as datetime
  • last_reconfiguration: Last BIRD config change as datetime

Test suite

There is a series of tests in tests.py. This includes a MockBird: a mocked BIRD instance, with fixed but real responses, that listens on a real UNIX socket. This means the tests do not only test parsing, but also socket interaction.
