Parameters
acl-number: ACL number to be used in the BSR filtering policy, in the range of 2000 to 2999.
Description
Use the bsr-policy command to limit the range of legal BSRs to prevent BSR spoofing.
Use the undo bsr-policy command to restore the default.
By default, no range limit is configured, namely all received messages are considered legal.
The source keyword in the rule command is translated into BSR address in the bsr-policy command.

to become BSR.
