Command Mode Router OSPF Configuration mode. User Guidelines OSPF is only enabled on an interface if the primary IPv4 address on the interface matches a network area range. Any individual interface can only be attached to a single area. If an interface address matches multiple network area ranges, the interface is assigned to the area for the first matching range. If the ip ospf area command is given for an interface, it overrides any matching network area command. OSPF only advertises IP subnets for secondary IP addresses if the secondary address is within the range of a network area command for the same area as the primary address on the same interface. When a network area command is deleted, matching interfaces are reevaluated against all remaining network area commands. Example console(config-router)#network 10.50.50.0 0.0.0.255 area 4 nsf Use this command to enable OSPF graceful restart. Use the no form of this command to disable graceful restart. Syntax nsf [ ietf ] [ planned-only ] no nsf [ietf] 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).
