Hello,

Well, I sat down to write the configuration and got immediately stuck: here's the thing: I have a pipe exporting from kernel tp given FIB, but in kernel I already have a default route from most preferable uplink - A, and I need a default route from B, which just isn't in the kernel. How do I deal with that ?

Thanks.

Hi,

Just use import filters in pipes exporting to your FIBs. To distinguish uplinks, while applying priorities, use if condition on source protocol's value or last ASN.

Best regards,

Lukasz

Hello,

I have a bird router serving multiple BGP sessions with my AS uplinks,
and now I need to create a more complicated thing, - I have several FIBs
and I need to reorder the BGP link preference for a given FIB. Say, I
have 3 uplinks, A/B/C, A is the most preferable one for default FIB, but
I need B to be the most preferable one for FIB 1. I have some basic
experience with multiple routing tables in bird, I'm successfully using
two at the moment, but I just have no idea on how to do this. I mean I
know how to make the B upstream the only channel for FIB 1 (without
redundancy), but I have no idea on how to reorder the preference in
order to keep the redundancy. Is there such a way ?


Thanks.

Eugene.
