When FRR runs under FIB 1 it means that all the connections with peers will be
done from that FIB. Nothing more. If you want to import routes from
non-standard fib (FIB ≠ 0) then use option "ip import table" instead, which
should also work when you will run FRR under default FIB.
I don't know if our FRR port supports multiple routing tables correctly, but
definitely net/bird2 copes fine with them.

That's probably not a bug though, but I have not investigated this PR
extensively.
