| Parameter | Description | Value |
|---|---|---|
| process-id | Specifies the ID for an OSPFv3 process. If the process number is not specified, information about all OSPFv3 processes is displayed in an ascending order. | The value is an integer that ranges from 1 to 65535. |
| interface-type interface-number | Specifies the name, type and the number of the interface. |
- |
| neighbor-id | Specifies router ID of the neighbor. | - |
| verbose | Displays detailed information of the neighbor. | - |
| all | Displays all the BFD sessions configured in OSPFv3. | - |
BFD can provide millisecond-level fault detection. BFD can work with OSPFv3 to rapidly detect faults on neighboring devices, and instruct OSPFv3 to recalculate routes for correct packet forwarding. You can run the command to check BFD session parameters in OSPFv3 processes.
