TABLE 69

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.
