The set protocols pimsm4 bootstrap cand-bsr scope-zone cand-bsr-by-vif-addr command configures the IP address of a VLAN interface or loopback interface to use as the C-BSR in a multicast scope zone.


Command Syntax

set protocols pimsm4 bootstrap cand-bsr scope-zone <IPv4Net> cand-bsr-by-vif-addr <IP-address>


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.

cand-bsr-by-vif-addr <IP-address>

Specifies the IP address of a VLAN interface or loopback interface to use as the C-BSR.

NOTE:

To avoid frequent protocol changes caused by interface flapping, using loopback interfaces is recommended.


Usage Guidelines

One or more C-BSRs need to be configured in a PIM-SM domain. A BSR is elected from C-BSRs. When multiple C-BSRs take part in the BSR election in the PIM-SM domain, the priority and IP address of the C-BSRs are used to in the BSR election process:

  1. If the C-BSRs have different priorities, the C-BSR with the highest priority (largest priority value) is elected as the BSR.
  2. If the C-BSRs have the same priority, the C-BSR with the largest IP address is elected as the BSR.


Example

  • Configure the IP address of a VLAN interface to use as the C-BSR in a multicast scope zone to 10.10.61.10.
