show ip ospf interface

Example

This example shows how to display all OSPF related information for VLAN 1:

System(rw)->show ip ospf interface vlan1
Vlan  1 is UP
 Internet Address  182.127.63.2  Mask  255.255.255.0,Area 0.0.0.0
 Router ID 182.127.64.1,Network Type BROADCAST,Cost: 10
 Transmit Delay is 1 sec,State BACKUPDR,Priority 1
 Designated Router id 182.127.62.1, Interface addr 182.127.63.1
 Backup Designated Router id 182.127.63.2,
 Timer intervals configured, Hello 10,Dead 40,Wait 40,Retransmit 5
    Neighbor Count is 1, Adjacent neighbor count is 1
  Adjacent with neighbor 182.127.63.1 (Designated Router)

show ip ospf interface Output Details provides an explanation of the command output.

show ip ospf interface Output Details

Output...	What it displays...
Vlan	Interface (VLAN) administrative status as up or down.
Internet Address	IP address and mask assigned to this interface.
Router ID	Router ID, which OSPF selects from IP addresses configured on this router.
Network Type	OSPF network type, for instance, broadcast.
Cost	OSPF interface cost, which is either default, or assigned with the ip ospf cost command. For details, refer to ip ospf cost.
Transmit Delay	The number (in seconds) added to the LSA (Link State Advertisement) age field.
State	The interface state (versus the state between neighbors). Valid values include BACKUPDR (Backup Designated Router), and DR (Designated Router) and Drother.
Priority	The interface priority value, which is either default, or assigned with the ip ospf priority command. For details, refer to ip ospf priority.
Designated Router IP	The router IP of the designated router on this subnet, if one exists.
Backup Designated Router IP	IP address of the backup designated router on this interface, if one exists.
Timer intervals configured	OSPF timer intervals. These are either default, or configured with the ip ospf retransmit-interval (ip ospf retransmit-interval), the ip ospf hello-interval (ip ospf hello-interval), and the ip ospf dead interval (ip ospf dead-interval) commands. The wait timer represents the amount of time a router waits before initiating a designated router/backup designated router election. The wait timer changes when the dead interval changes. The retransmit timer represents the amount of time between successive transmissions of LSAs (Link State Advertisements) until acknowledgement is received.
Neighbor Count	Number of neighbors over this interface.
Adjacent neighbor count	Number of adjacent (FULL state) neighbors over this interface.
Adjacent with neighbor	IP address of the adjacent neighbor.
