set protocols pim interface unicast-bsm

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

The delete protocols pim interface unicast-bsm command is used to restore the default configuration.

Command Syntax

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

delete protocols pim interface <interface-name> unicast-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 unicast bootstrap messages. The value is enable or disable.

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

The default value is enable.

Usage Guidelines

By enabling or disabling the processing of unicast bootstrap messages on a PIM interface, network administrators can control how the interface participates in the PIM-SM (Sparse Mode) Bootstrap Router mechanism. Enabling unicast BSM handling allows the interface to participate in the dynamic election of RPs and BSRs using unicast messages, improving multicast routing efficiency and resilience. Disabling it can be useful for optimizing network performance and ensuring the correct handling of multicast traffic based on specific network design requirements.

Example

Enable the PIM interface to process unicast bootstrap messages.
