[c-nsp] Conflicting OSPF router-ids in separate VRFs

Thanks for the reply.  This sounds odd to me.  Why wouldn't IOS be able 
to handle conflicting OSPF router-ids for OSPF processes in different 
VRFs?  I could certainly see the problem if these were separate OSPF 
processes that were in the global VRF but I would think that VRF 
separation would take care of any conflicts in OSPF processes.  Odd.  Is 
this something that may be addressed in a future release?

Thanks again for the reply
