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
Example
...
run show command initiates a graceful restart for all OSPF instances configured with the “set protocols ospf [instance-id <instance-id> | vrf<] [vrf<vrf-name>] interface [traffic | an-interface <vlan-interface>]
Parameters
...
interface<traffic>
...
graceful-restart enable true” command. The ospfd daemon should be restarted during the instance-specific grace period, otherwise the graceful restart will fail.
To perform a graceful shutdown, this operational command needs to be issued before restarting the ospfd daemon.
Command Syntax
run graceful-restart prepare ospf
Parameters
None.
Example
- Initiate a graceful restart for all OSPF instances.
