display ospf brief
Parameters
| Parameter | Description | Value |
|---|---|---|
| process-id | Specifies the ID of an OSPF process. If no OSPF process ID is specified, brief information about all the OSPF processes is displayed. |
The value is an integer ranging from 1 to 65535. |
Usage Guidelines
Configure Router ID
Configure VPN domain ID
When locating OSPF faults, you can run the display ospf brief command to obtain OSPF brief information. You can then analyze OSPF faults according to the brief information.
Example
# Display OSPF brief information.
