Patch to fix BGP ghost routes resulting from loops
by Ivo Smits 04 Apr '11

04 Apr '11

I've created attached patches to prevent BGP route loops from turning into ghosts (issue reported earlier to the mailing list: http://marc.info/?l=bird-users&m=129433651229774&w=2) Instead of completely ignoring received BGP routes containing the router's own AS number, it should now handle them as if the prefixes are unreachable. We have tested the patch against git and it fixed the issue there. I've also made an (untested) patch against bird 1.2.5. -- Ivo

source address for routes installed in routing table (on linux)
by Arkadiusz Miskiewicz 03 Apr '11

Hello, bird installs routes in kernel table without any source address, so for all connections initiated at that machine kernel chooses address from interface. I'm looking for a sane way to get routes installed with specific source address - basically an equivalent of "ip r a x.y.z.q/prefix via nexthop dev ethX src MYIP" command. I don't see such functionality in bird (so consider this to be a feature request). From irc I see that there are hacky way to get archieve that but these are just hacky (adding ipv4 address with scope link or preferred_lft 0 for ipv6). -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/
