Ah, you said rib. Did look at the code a bit more.
It looks like there is a "dump routes" command. Might
try that.
Here it says "birdc" can do some stuff...
http://bird.network.cz/?get_doc&f=bird-4.html
dump resources|sockets|interfaces|neighbors|attributes|routes|protocols
and
show route [[for] prefix|IP] [table sym] [filter f|where c]
[(export|preexport) p] [protocol p] [options]
/jgk
