Hi Ondrej,

Thanks for your help. I've changed as you suggested on sysdep/bsd/krt-sock.c to PROTO2 and i worked fine.

I'd would like know what kind of problem i would have if i keep this change on my bird. Can i run into some issues with other protocols or systems?

Thanks.

Hello

On BSD systems, BIRD uses PROTO1 route flag to identify 'its' routes. If
OpenBGP uses the same flag, then they mix-up their routes. Currently
there is no option in BIRD to change it to use PROTO2 or PROTO3 flag [*],
i don't know about OpenBGP. I wonder if there is a better way to
distinguish route ownership in BSD systems (like there is u8 rtm_protocol
field in Linux).


[*] Could be changed in the source code on these lines in
sysdep/bsd/krt-sock.c:

msg.rtm.rtm_flags = RTF_UP | RTF_PROTO1;
...
u32 self_mask = RTF_PROTO1;
