Run the command The run graceful-restart prepare ospf 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
...
interface<traffic>
...
Example
...
command is a operational command that the restarting router advertises Graceful Restart (GR) LSAs into the OSPF domain, informing its neighbors about its restarting process and the estimated time for the restart to complete. These LSAs are Type 9 LSAs and are flooded throughout the OSPF domain.
The OSPF protocol should be restarted during the grace period, otherwise the graceful restart will fail.
To perform a graceful shutdown, this operational command needs to be issued before restarting the OSPF protocol.
