	•	ietf — This keyword is used to distinguish the IETF standard
		implementation of graceful restart from other implementations. Since
		the IETF implementation is the only one supported, this keyword is
		optional
	• planned-only— This keyword indicates that OSPF should only
		perform a graceful restart when the restart is planned (i.e., when the
		restart is a result of the initiate failover command).
	Default: Graceful restart is disabled by default.
nsf helper [ planned-only ]	Use this command to allow OSPF to act as a helpful neighbor for a
	restarting router. Use the “no” form of this command to prevent OSPF
	from acting as a helpful neighbor.
		•	planned-only— This keyword indicates that OSPF should
			only help a restarting router performing a planned restart.
	Default: OSPF may act as a helpful neighbor for both planned an
	unplanned restarts.
nsf [ietf] helper strict-lsa-checking	This command is used to require that an OSPF helpful neighbor exit
	helper mode whenever a topology change occurs. Use the “no” form of
no nsf [ietf] helper strict-lsa-checking	this command to allow OSPF to continue as a helpful neighbor in spite of
	topology changes.
	Default: A helpful neighbor exits helper mode upon a topology change.
nsf [ietf] restart-interval seconds	Use this command to configure the length of the grace period on the
	restarting router. Use the “no” form of this command to revert the grace
	period to its default.
	• ietf — This keyword is used to distinguish the IETF standard

		the IETF implementation is the only one supported, this keyword is
		optional.
	• seconds — The number of seconds that the restarting router asks its
		neighbors to wait before exiting helper mode. The restarting router
		includes the restart interval in its grace LSAs (range 1 – 1800
		seconds).
	Default: The default restart interval is 120 seconds.
show ip ospf	This command has been enhanced to lists the values of the configuration
	parameters described above and the status parameters defined in the
