Displaying OSPF information
Displaying OSPF graceful restart information
To display OSPF graceful restart information for OSPF neighbors, use the show ip ospf neighbors
command.
Brocade#show ip ospf neighbors
Port Address Pri State Neigh Address Neigh ID Ev Opt Cnt
1/1/2 192.168.50.10 0 FULL/OTHER 192.168.50.1 10.10.10.30 21 66 0
< in graceful restart state, helping 1, timer 60 sec >
Syntax: show ip ospf neighbor
Use the following command to display Type 9 grace LSAs on a Brocade Layer 3 switch.
Brocade#show ip ospf database grace-link-state

TABLE 41 CLI display of OSPF database grace LSA information
Field Definition
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 The 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
FastIron and other OSPF routers to determine the most recent LSA for a
given route.
Prd The grace period. The number of seconds that the neighbor routers
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 begins when the grace LSA LS age is
equal to 0, the grace period terminates when either the LS age of the
grace LSA exceeds the value of a grace period or the grace LSA is flushed.
Rsn The reason for the graceful restart. Possible values:
•
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.
