OSPF Commands
1107
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

command to disable graceful restart.
Syntax
nsf [ ietf ] [ planned-only ]

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).
