[c-nsp] mpls ip creating traffic disturbance(s)

[Eric A Louie]

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
