Hello all,
I have understand the difference between NSF and NSR. NSF supports forwarding without traffic loss during a brief outage of the control plane. Whereas NSR allows for the forwarding of data packets to continue along known routes while the routing protocol information is being refreshed following a processor switchover.
Would like to know
1. Working principle of Graceful restart.
2. Do we need to enable gracefule restart along with NSF abd NSR?
3. What is the advantage of enabling Graceful restart with NSR?
4. If possible, please explain what is checkpointing and mirroring?
Thanks
Hari
