[c-nsp] T1 MLPPP causing OSPF to crash

[Chris Lane]

I have bonded two t1's yesterday using MLPPP, and today the customer is
testing the link. We have a 2620 at the customer facility and a 7206VXR at
our facility. When the customer went to test the link, it caused our 7206 to
crash OSPF with our backbone.
Here is a snapshot of our logs:
