interval-value: Specifies the Graceful Restart interval, in the range 40 to 1,800 seconds. 

Use the graceful-restart interval command to configure the Graceful Restart interval.  

Use the undo graceful-restart interval command to restore the default Graceful Restart interval. 

By default, the Graceful Restart interval is 120 seconds. 

Note that the Graceful Restart interval of OSPF cannot be less than the maximum value of dead 

intervals on all OSPF interfaces; otherwise, the Graceful Restart of OSPF may fail.
