igmp-snooping proxy-uplink-port vsi

Function

The igmp-snooping proxy-uplink-port vsi command configures an interface as an IGMP snooping proxy uplink interface. No IGMP Query message can be sent to this interface.

The undo igmp-snooping proxy-uplink-port vsi command cancels the configuration.

By default, no IGMP snooping proxy uplink interface exists in a VSI.

Usage Guidelines

Usage Scenario

After the IGMP snooping proxy or querier function is enabled on a Layer 2 device, the Layer 2 device broadcasts IGMP Query messages to all interfaces (including router interfaces) in a VLAN/VSI/BD periodically, which may trigger IGMP querier reelection. To prevent IGMP querier reelection, run the igmp-snooping proxy-uplink-port command on the router interface to disable the Layer 2 device from sending IGMP Query messages to the router interface in a VSI.

Prerequisites

IGMP snooping proxy has been enabled using the igmp-snooping proxy in the VLAN/VSI/BD view, or IGMP snooping querier has been enabled using the igmp-snooping querier enable command in the VSI view.

Precautions

Only one IGMP snooping proxy unlink interface can be configured in a VSI.

For a VSI, the igmp-snooping proxy-uplink-port command can be only used on a VSI in LDP mode or the leaf node of a VSI in BGPAD mode.

Example

# Configure a GE 0/1/1 in VSI vsi1 as an IGMP snooping proxy uplink interface.
