[c-nsp] Community tagged route, redistributed to RR, but OSPF "learnt" route takes precedence(So RIB failure)

To the best of my knowledge, there's a completely independent "BGP RIB", 
where all BGP routes go to live/die. Therefore, RIB failure doesn't 
prevent propagation.

Does the RR consider this path its best path for this route? If not, it 
won't reflect it. Otherwise, I'd verify that you have reflection 
configured as intended, and that you don't have an outbound route map 
that might be discarding the route.

Is there anyway "around" this...i.e. I want to maintain OSPF advertising default to the RR, but the RR to advertise a "different" default learnt from another PE, to a RR-Client......hopefully that makes sense :)
