Modes
OSPF Router Configuration
nsf restart-interval
Use this command to configure the number of seconds that the restarting router asks its
neighbors to wait before exiting helper mode. This is called the "grace period." The restarting
router includes the grace period in its grace LSAs. For planned restarts (using the initiate
failover command), the grace LSAs are sent prior to restarting the management unit,
whereas for unplanned restarts, they are sent after reboot begins. The grace period must be
set long enough to allow the restarting router to reestablish all of its adjacencies and
complete a full database exchange with each of those neighbors.
Default
120 seconds

nsf [ietf] restart-interval <1-1800>

Description

seconds

exiting helper mode. The range is from 1 to 1800 seconds.
