Description (partial)

Symptom:
When vrf configuration on multicast protocols such as PIM is changed between "default" and "non-default" vrf multiple times, we can experience an mrib process crash.

Conditions:
This is caused by uncommon sequence of "default" and "non-default" vrf configurations of multicast protocols such as PIM. This only occurs if BVI interfaces are also configured for multicast.
