no summarization (yet), Andrew.  This is all inside an ospf area 0 network.

 Much appreciated, Eric

Do you do any IP address summarisation in your network? Summarisation breaks 
forwarding in MPLS networks.

We implemented what seemed to be a pretty simple mpls configuration to test a 
vrf config.

It caused widespread havoc across my production network.

Has anyone encountered a situation where they've put "mpls ip" on a link and had 

it cause problems with web browsing to the Internet, even on traffic that passed 

through the router that was not going through the mpls ip interfaces?

I have a case open with Cisco TAC but was looking for some additional guidance 
and perhaps some experience around this strange problem.

Much appreciated, Eric
