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. You can also specify a particular interface to show information related to that L3 interface.

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 [instance-id <instance-id> | vrf<vrf-name>] interface [traffic | an-interface <vlan-interface>]

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>	Optional. Specifies the name of the VRF. The value is a string.
interface<traffic>	Show traffic related to OSPF interfaces.
an-interface <vlan-interface>	Specify a L3 interface, the value is a string. It can be the VLAN interface name, the routed interface or the sub-interface name.

Example

Show OSPF interface related information in OSPF instance ID 1.
