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.
