BIRD is an Internet Routing Daemon designed to support all the routing
technology used in the today's Internet or planned to be used in near
future and to have a clean extensible architecture allowing new routing
protocols to be incorporated easily. Among other features, BIRD supports:

* both IPv4 and IPv6 protocols
* multiple routing tables
* the Border Gateway Protocol (BGPv4)
* the Routing Information Protocol (RIPv2)
* the Open Shortest Path First protocol (OSPFv2)
* a virtual protocol for exchange of routes between different routing
  tables on a single host
* a command-line interface allowing on-line control and inspection of
  status of the daemon
* soft reconfiguration (no need to use complex online commands to
  change the configuration, just edit the configuration file and notify
  BIRD to re-read it and it will smoothly switch itself to the new
  configuration, not disturbing routing protocols unless they are
  affected by the configuration changes)
* a powerful language for route filtering

BIRD has been developed at the Faculty of Math and Physics, Charles
University, Prague, Czech Republic as a student project. It can be
