effectively guarantee high BSR security.
The source keyword in the rule command is translated into BSR address in the
bsr-policy command.
Related command: acl, rule.

6.1.2 c-bsr

Syntax
c-bsr interface-type interface-number hash-mask-len [ priority ]
undo c-bsr
View
PIM view
Parameter
interface-type interface-number: VLAN interface. The candidate BSR is configured on
the VLAN interface. PIM-SM must be enabled on the VLAN interface first.
hash-mask-len: Length of the mask. The value ranges from 0 to 32.
priority: Priority of the candidate BSR. The greater the value of the priority, the higher
the priority of the BSR. The value ranges from 0 to 255. By default, the priority is 0.
Description
Use the c-bsr command to configure a candidate BSR.
Use the undo c-bsr command to remove the candidate BSR configured.
By default, no candidate BSR is set.
For the configuration of the candidate BSR, the larger bandwidth should be guaranteed
since a large amount of information will be exchanged between BSR and other devices
in the PIM domain.
