run show ospf interface

Run the command run show ospf interface to display information about layer 3 interfaces participating in OSPF process. The command output displays information such as interface name, IP address, the area this interfaces belongs to, neighbor adjacency count, multicast group memberships and OSPF timers etc.

To display the interface traffic related to OSPF, add the argument traffic to the command. This will display information such as OSPF hello messages sent and received on the interface, database description messages sent and received 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.

Command Syntax

run show ospf [vrf <vrf-name>] interface [traffic]

Example

Enable OSPF zebra module related logging.
