Hi everyone, I've recently setup bird 1.0.11 on a Linux system. I've defined my static routes likes this: protocol static { route x.y.z.0/27 via "eth3"; route x.y.z+1.0/24 via "eth2"; route x.y.z+2.0/24 via "eth2"; route x.y.z+5.0/25 via "eth2"; route x.y.z+5.128/26 via "eth2"; route x.y.z+5.192/28 via "eth2"; route x.y.z.0/20 drop; } I have a /20 allocation from the RIPE NCC, which is x.y.z.0/20 I have configured my BGP as follows: protocol bgp { local as MYASN; neighbor a.b.c.d as REMOTE-AS; path metric 1; # Prefer routes with shorter paths (like Cisco) source address e.f.g.h; # local address TCP connection export where source=RTS_STATIC; import all; } This works, and I see x.y.z.0/20 advertised, if I look through a looking glass router. However, what I am not clear about is this: does bird actually export _all_ the static routes I have defined? And are they simply not visible because my upstream is filtering them? Or is bird actually clever enough to see that x.y.z.0/20 is an aggregate of all the other routes, and only advertises the one route? And what do other users recommend? Is my setup ok, or is it better if I change the export line to actually export only the one prefix? Regards, Anand
