Although more convenient it's not a hard requirement, router can forward using IP header you just need to make sure the backup router prefers locally introduced eBGP routes before iBGP routes advertised by primary router. Also I don't ever see a need for per-prefix labels -certainly doing that for the Internet VRF would be madness. Using per next-hop labels is sufficient to avoid lookup in this case -but then things like IP FW filters are bypassed. adam
