Configuring DR Priority of an Interface
Context
The DR priority on a router interface qualifies the interface for the DR election. If the DR priority is 0, the router cannot be elected as a DR or BDR.
Do as follows on the router that runs OSPFv3.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run ospfv3 dr-priority priority [ instance instance-id ]
The DR priority of the interface is set.
Follow-up Procedure
After the DR priority is changed, you can re-elect a DR or BDR through the following methods, which, however, will result in the interruption of the OSPFv3 neighbor relationship between routers and therefore are used only when necessary.
Restarting all routers.
Running the shutdown and undo shutdown commands on the interface on which the OSPFv3 neighbor relationship is set up.
