set protocols pim interface bsm

The set protocols pim interface bsm command is used to configure the handling of bootstrap messages (BSM) on a specific VLAN interface for Protocol Independent Multicast (PIM).

The delete protocols pim interface bsm command restores the default configuration.

Command Syntax

set protocols pim interface <interface-name> bsm <enable | disable>

delete protocols pim interface <interface-name> bsm

Parameter

Parameter

Description

interface <interface-name>

Specifies an L3 interface. The value could be a VLAN interface name, loopback interface name, routed interface or sub-interface name. The value is a string.

<enable | disable>

Enables or disables the PIM interface to process bootstrap messages. The value is enable or disable.

enable: enables the PIM interface to process bootstrap messages.
disable: disables the PIM interface to process bootstrap messages.

The default value is enable.

Usage Guidelines

By enabling or disabling the processing of bootstrap messages on a PIM interface, network administrators can control how the interface participates in the PIM-SM (Sparse Mode) Bootstrap Router mechanism. Enabling BSM handling allows the interface to participate in the dynamic election of RPs and BSRs, improving multicast routing efficiency and resilience.

NOTE:

When the PIM-SM Bootstrap Router mechanism is enabled to dynamically elect an RP, the PICOS switch can receive C-RP advertisement messages sent by other PIM switches. It can then calculate and compare these messages to elect the RP for a specific group from multiple C-RPs. However, the PICOS switch itself does not participate in the election as a BSR or dynamic RP.

Example

Enable the PIM interface to process bootstrap messages.
