[c-nsp] RIB-failure(2) - next-hop mismatch - In VRF context

[Adam Vitkovsky]

Hi folks,

I'd like to ask what is the meaning of "RIB-failure(2) - next-hop mismatch"
- in context of a VRF table please

#sh ip b vpnv4 vrf voice1 10.100.2.0
BGP routing table entry for 16160:402:10.100.2.0/28, version 22965354

We tried changing the RT and it didn't work, we also tried advertising the
route from a different PE(NH) which obviously did the trick. 
We did not clear the process or rebooted the router to rule out memory
issues or table allocation problems.
And obviously there are plenty of other routes with the same NH in this VRF
and they are all fine.
