Bird is a commonly used BGP daemon. This page provides configuration and help to run Bird for dn42. # Simplest configuration possible TODO ## Source address selection Bird, like any other routing daemon, inserts routes into the kernel. If you don't specify a source address on the kernel routes, then the kernel will choose for you (and will often choose an address in a transfer subnet, which is not what you want). To specify the source address, you use the `krt_prefsrc` attribute, for instance in the export filter of the kernel protocol: protocol kernel { export filter { krt_prefsrc = 2001:db8:42::1; accept; }; } (this also works for IPv4) # Example advanced configurations Paste your own config template here. ## External links http://danrimal.net/doku.php?id=wiki:bgp:bird:sample_configs2
