Yea, I do have 6VPE deployed on the other network that we run, and there are no problems there. 

As for 6PE problems I'm having now..

TAC hasn't gotten back to us yet, but on the other somewhat related bug seems to be CSCuo20651 affecting both v4 and v6 labeled-ucast.
It suggests doing 'clear route ipv6 unicast' as a workaround to force reprogramming of v6 (6pe included) routes into FIB.
