run show ospf neighbor
Run the command run show ospf neighbor  to display the OSPF neighbor devices. The command output displays the neighbor router ID, State, Dead Time, Address and Interface etc.
If OSPF is running in the default VRF then no need to specify the VRF but if OSPF is running in a user defined VRF then you need to specify the VRF by using the vrf parameter.
Optional parameter instance-id can be included to specify the OSPFv2 multi-instance ID in the default VRF.
If you require more detail about OSPF neighbors then add the argument detail to the command which will display information about the OSPF area the neighbor belongs to and recent state change statistics etc.
Command Syntax
run show ospf [instance-id <instance-id> | vrf <vrf-name>] neighbor [detail]
Parameters
Parameter | Description |
instance-id <instance-id> | Optional. Specifies the OSPF instance ID in the default VRF. The value is an integer that ranges from 1 to 8. |
vrf <vrf-name> | Specifies the VLAN interface name. |
