The router-id command sets the Router ID for the router that runs OSPFv3.
The undo router-id command deletes the Router ID that is set for OSPFv3 router.
| Parameter | Description | Value |

| router-id | Indicates the Router ID in dotted decimal notation. | - |
The Router ID of an OSPFv3 process is unique in an AS. If no Router ID is set, the OSPFv3 process does not run.
When you set a Router ID, ensure that the Router IDs of any two processes are different in an AS.
Multiple OSPFv3 processes can run on a router by setting the different process ID. In this case, you need to specify different Router IDs for different processes.
