I had a multi-VRF Multicast configuration going using the following document for configuration:
I rebooted both routers that peered via iBGP after an IOS upgrade. The BGP peer would come up, LDP neighbor relationship would come up. As soon as that tunnel would come back up, all traffic would stop and the peer would disassociate. No traffic whatsoever would pass. Any recommendations?

Im working on a viewable version of the config. It's really huge. Im using multiple loopbacks for bgp peering on the vrf's, but using loop0 for the main bgp peer. Working on the config.

i am not getting any improper configuration from your post. What i am thinking off that the problem with the RPF only. Please check the RPF is it succeeded or not.
Becaseu you r having one MP-BGP peering ; if u have more than one BGP peering in your cloud then the problem comes.
