Default Format Modes Disabled nsf [ietf] [planned-only] OSPF Router Configuration Parameter ietf planned-only Description This keyword is accepted but not required. This optional keyword indicates that OSPF should perform only a graceful restart when the restart is planned (that is, when the restart is a result of the initiate failover command). no nsf Use this command to disable graceful restart for all restarts. Format Modes no nsf 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 Format Modes 120 seconds nsf [ietf] restart-interval OSPF Router Configuration Parameter ietf seconds Description This keyword is accepted but not required. The number of seconds that the restarting router asks its neighbors to wait before exiting helper mode. The range is from 1 to 1800 seconds. Routing Commands 306
