The restarting router sends the EOR marker, indicating the end of a routing update and the end of the graceful restart.
The restart timer defined by the restarting router expires.
The stale-route-time timer defined on the receiving router expires.
If the receiving router receives RIB updates and the EOR marker before the timers expire, it updates the local RIB and deletes any stale entries. If either of the timers on the receiving router expires before the receiving switch receives the EOR marker from the restarting switch, all stale routes are deleted.
