Using the show ip ospf command you can display the current OSPF Router Advertisement
configuration. The text show below in bold is displayed for an OSPF Router Advertisement
configuration.

TABLE 35 CLI display of OSPF database grace link state information
This field... 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.
