BIRD is a dynamic IP routing daemon supporting both, IPv4 and IPv6, Border Gateway Protocol (BGPv4), Routing Information Protocol (RIPv2, RIPng), Open Shortest Path First protocol (OSPFv2, OSPFv3), Babel Routing Protocol (Babel), Bidirectional Forwarding Detection (BFD), IPv6 router advertisements, static routes, inter-table protocol, command-line interface allowing on-line control and inspection of the status of the daemon, soft reconfiguration as well as a powerful language for route filtering.
