BIRD是一个类UNIX系统的动态路由守护进程。它支持当代互联网中所用所有路由协议，如BGP、OSPF、RIP和这些协议的IPv6的变种(除OSPFv3目前尚在发展)。此外它还采用了非常灵活的配置机制，以及一个路由过滤语言。
BIRD is a dynamic routing daemon for UNIX-like systems. It should support all routing protocols used in the contemporary Internet, such as BGP, OSPF, RIP, and their IPv6 variants (except for OSPFv3 which is still under development). It also features a very flexible configuration mechanism, and a route filtering language.
Features
* Both IPv4 and IPv6 (use --enable-ipv6 when configuring)
* Multiple routing tables
* BGP
* RIP
* OSPF
* Static routes
* Inter-table protocol
* Command-line interface (using the `birdc' client; to get some help, just press
* Soft reconfiguration -- no online commands for changing the configuration in very limited ways, just edit the configuration file and issue a `configure' command or send SIGHUP and BIRD will start using the new configuration, possibly restarting protocols affected by the configuration changes
* Powerful language for route filtering
最新版本：1.4
支持 OSPF 和 BGP 的 BFD，BGP 新的参数：'allow local as' ，gw、ifname 和 ifindex 设置支持过滤器,；增加 -P 参数来支持 PID 文件；-f 参数来强制 BIRD 在前台运行。
