Hello Nishant,

in first implementation of OSPF as PE-CE the limit was counted against the max number of OSPF processes on the box and was in the order of 30.

A successive implementation has removed this limit for VRF OSPF instances.

Thanks Giueseppe.

I have gone through the links and found one ambigious statement."Only 32 processes per VRF can be supported. For different VRF processes, there is no limit. "

Can you elaborate on this statement?

Appreciate your help
