set protocols pimsm4 bootstrap cand-bsr scope-zone hash-mask-len

The set protocols pimsm4 bootstrap cand-bsr scope-zone hash-mask-len command configures the hash mask length that is used in the hash calculation for the dynamic RP election.

Command Syntax

set protocols pimsm4 bootstrap cand-bsr scope-zone <IPv4Net> hash-mask-len <hash-length>

Parameter

Parameter

Description

scope-zone <IPv4Net>

Specifies a range of multicast scope zone that can serve on the C-BSR. The value can be any sub-range of 224.0.0.0/4.

hash-mask-len <hash-length>

Specifies the hash mask length.

The value is an integer that ranges from 4 to 32. The default value is 30.

Usage Guidelines

During dynamic RP election, if C-RPs have the same interface address and priority for a specified multicast group, a hash function needs to be calculated to select the RP for the multicast group. The switch performs hash calculation for the group address of G, C-RP address, and hash mask length of the C-RPs with the same priority and compares the hash values. The C-RP with the greatest hash value acts as the RP for the G. The hash mask length is used to adjust the hash calculation result.

Example

Set the hash mask length in scope zone 239.0.0.0/8 to 16.
