Displaying OSPF virtual link information
Use the show ip ospf virtual link command to display OSPF virtual link information.
device# show ip ospf virtual link
Indx Transit Area Router ID Transit(sec) Retrans(sec) Hello(sec)
1 1 131.1.1.10 1 5 10
Dead(sec) events state Authentication-Key
40 1 ptr2ptr None
MD5 Authentication-Key: None
MD5 Authentication-Key-Id: None
MD5 Authentication-Key-Activation-Wait-Time: 300
Syntax: show ip ospf virtual link [ num ]
The num parameter displays the table beginning at the
specied entry number.
Clearing OSPF neighbors
You can clear all OSPF neighbors or a specied OSPF neighbor using the following command.
device# clear ip ospf neighbor all
Syntax: clear ip ospf neighbor { all | ip-address }
Selecting the all option clears all of the OSPF neighbors on the router.
The ip-address variable allows you to clear a specic OSPF neighbor.
Displaying OSPF Graceful Restart information
To display OSPF Graceful Restart information for OSPF neighbors use the show ip ospf neighbors command as shown in the following.
device# show ip ospf neighbors
Port Address Pri State Neigh Address Neigh ID Ev Opt Cnt
2/7 50.50.50.10 0 FULL/OTHER 50.50.50.1 10.10.10.30 21 66 0

Area The OSPF area that the interface congured for OSPF graceful restart is
in.
Interface The interface that is congured 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
