Displays...

Area

The OSPF area that the interface configured for OSPF graceful restart is
in.

Interface

The interface that is configured for OSPF graceful restart.

Adv Rtr

ID of the advertised route.

Age

The age of the LSA in seconds.

Seq(Hex)

The sequence number of the LSA. The OSPF neighbor that sent the LSA
stamps the LSA with a sequence number. This number enables the
device and other OSPF routers to determine which LSA for a given route
is the most recent.

Prd

Grace Period: The number of seconds that the router's neighbors should
continue to advertise the router as fully adjacent, regardless of the state
of database synchronization between the router and its neighbors.
Since this time period began when grace-LSA's LS age was equal to 0,
the grace period terminates when either:

the LS age of the grace-LSA exceeds the value of a Grace Period

the grace-LSA is flushed.

Rsn

Graceful restart reason: The reason for the router restart defined as one
of the following:

UK – unknown

RS – software restart

UP – software upgrade or reload

SW – switch to redundant control processor

Nbr Intf IP

The IP address of the OSPF graceful restart neighbor.
