[j-nsp] source-based routing/vrf

[Jonas Frey]

Hello,

i've got the following setup:

3 Carriers: A, B, C
2 Prefixes: 10.0.0.0/24, 10.0.1.0/24

What should be accomplished:
Carrier A should be always prefered (via local-pref etc.)

If the source is prefix 10.0.0.0/24 then Carrier B (after Carrier A)
should be used, however in case Carrier B is dead, Carrier C should be
used.
Same goes for prefix 10.0.1.0/24 but in the other direction:
Carrier C should used by default (after Carrier A), however if Carrier C
goes down, Carrier B should be used.

Not sure how to get this going, probably via vrf/rib-groups? Could
someone shed some light on this? Thanks.

Regards,
Jonas Frey
