Hi, I experiment strange behaviour (too, sorry I don't know OSPF) when using BGP. On one of my router I loose the interface route of one ethernet interface. It is used to a BGP connection : R1 - ethernet - R2 It seems that we've got the following phenomenom : - R2 send the interface route to R1 - bird on R1 put this route in the main table destroying the interface route. - bird on R1 detect that there's no route to R2 and stop the session (Netlink message) The configuration is symetric, R2 used also bird. There's no problem on R2, so the problem has to come from the difference in the configuration. R2 works with main table and R2 works with different table. Here's a : show protocols name proto table state since info kernel1 Kernel MAIN up Jul11 device1 Device MAIN up Jul11 direct1 Direct master up Jul11 static1 Static MAIN up Jul11 static2 Static ADSL up Jul11 pipe3 Pipe ADSL up Jul11 -> MAIN bgp1 BGP MAIN up Jul11 Established bgp2 BGP ADSL up Jul11 Established bgp3 BGP MAIN up Jul11 Established The configuration ot the pipe is : protocol pipe { table ADSL; peer table MAIN; import filter pas_nos_ips; export filter pas_nos_ips; } I can provide the complete conf if this explanation is not enough.
