Hmm.  Why do you query that? (asks a passive but interested observer to 
this conversation.)

(A week to explain, a week for them to lab it up and then I had to argue that it was wrong because they didn't even use a VRF, much less MPLS)  Can't reboot till next week and my head is still sore from the last tac case.
