The ospfv3 dr-priority command sets the priority of an interface that takes part in the DR or BDR election.
The undo ospfv3 dr-priority command restores the default value.
By default, the priority of an interface that takes part in the DR or BDR election is 1.
ospfv3 dr-priority priority [ instance instance-id ]
undo ospfv3 dr-priority [ priority ] [ instance instance-id ]
| Parameter | Description | Value |
|---|---|---|
| priority | Specifies the priority of the interface that candidates for DR or BDR. | The value is an integer ranging from 0 to 255. The default value is 1. |
| instance instance-id | Specifies the instance ID of the interface. | The value is an integer ranging from 0 to 255. The default value is 0. |
The priority of the interface determines the qualification of the interface when electing DR or BDR. The interface with the higher priority is preferred. The router whose priority is 0 cannot be elected as a DR or a BDR.
Before running this command on an interface, run the ospfv3 area command on the interface to enable OSPFv3.
