3.9.0.MCAST

Description (partial)

Symptom:

Some MoFRR routes switch over times goes beyond 50 milliseconds. In 
worst we have seen it goes up to 95 milliseconds. 

This is intermittent problem and does not happen all the time. We have
seen it happening once in every 20 iterations of switch overs of all 
the  routes. 

Conditions:

Scaled setup with 1024 MoFRR enabled routes. Once MoFRR enabled on
1024 routes, we have seen problem happening with few routes even 
after removing majority of the routes.
