I established an AS112 Server in my testbed using BIRD as the router. I setup a dummy interface on the AS112 server (bs) for all the subnets with an interface name that starts with 'as112_'. I set up the bird and bird6 configuration files identically except for the prefix 'set allnets' and or course the IPv4 remote addresses in bird.conf and IPv6 addresses in bird6.conf.
