It doesn't really go down as you would think if you powered it off...
It continues to forward packets using hardware and what's currently in
the RIB.

Books say in gracefull restart , if there are two neighbors.. the
router which is going down will send a gracefull msg to its peer and
that peer will not alter its routing table for specific period of
time and will continue forwarding packets to router which is going
down. and when the router which went down comes up will take all the
routes from its peer router.
I have confusion , if the router is going down how will it forward
packets coming from the peer ?
Could any1 clear the concept of gracefull restart , with a simple
example of two routers , I would be very thankfull ?
