The c-bsr priority command configures the global priority for a Candidate-BootStrap Router (C-BSR).
The undo c-bsr priority command restores the default configuration.
| 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. The default value is 0. |
Usage Scenario
When multiple C-BSRs take part in the BootStrap router (BSR) election in the PIM-SM domain, the following situations occur:
The FW with the highest priority wins in the BSR election.
In the case of the same priority, the FW 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
The multicast routing-enable command has been run.
Configuration Impact
If the c-bsr priority command is run several times, the latest configuration overrides the previous one.
Precautions
The global priority set using the c-bsr priority command is valid to all C-BSRs on the FW. To modify the priority of the C-BSR on an interface, run the c-bsr command.
The c-bsr command is valid only for a specified interface. When the two commands are used simultaneously, the system prefers the configuration done using the c-bsr command.
