The c-bsr priority command configures the global priority for a C-BSR.
The undo c-bsr priority command restores the default configuration.
By default, the global priority of the C-BSR is 0.
| Parameter | Description | Value |
|---|---|---|
| priority | Specifies the global priority of the C-BSR. The greater the value, the higher the priority of the C-BSR. | The value is an integer that ranges from 0 to 255. |
Usage Scenario
When multiple C-BSRs take part in the BSR election in the PIM-SM domain, the following situations occur:
The switch with the highest priority wins in the BSR election.
If they have the same priority, the switch with the largest IP address wins in the BSR election.
To enable a C-BSR to function as the BSR, you can run the c-bsr priority command to increase the priority value of the C-BSR.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
Precautions
You can run the c-bsr interface-type interface-number priority command in the PIM view to configure the C-BSR interface and specify the C-BSR priority. The c-bsr priority priority command specifies the global C-BSR priority. If both c-bsr interface-type interface-number priority and c-bsr priority priority are used, the c-bsr interface-type interface-number priority command takes effect.
