igmp-snooping send-query source-address (VLAN view)

Function

The igmp-snooping send-query source-address command sets a source IP address for the IGMP Query messages sent by a device.

The undo igmp-snooping send-query source-address command restores the default source IP address (192.168.0.1) of the IGMP Query messages sent by a device.

By default, the source IP address is not configured in VLAN.

Usage Guidelines

Usage Scenario

After IGMP snooping proxy or querier is enabled on a device in a Layer 2 broadcast domain, the device sends IGMP Query messages on behalf of the upstream Layer 3 router in the Layer 2 broadcast domain to collect user information. By default, the source IP address of the IGMP Query messages sent by the device is 192.168.0.1. In some scenarios, the IP address may be used by another device, or users require that the source IP address of IGMP Query messages be on the same network segment as the IP address of the local device. In this case, you can run the igmp-snooping send-query source-address command to set a source IP address for the IGMP Query messages sent by the device.

Precautions

If source IP addresses are set for the IGMP Query messages sent by the device both in a VLAN and globally, the configuration in the VLAN takes effect preferentially.

If no source IP address is configured for the IGMP Query messages sent by the device in a VLAN, the global configuration is used.

If source IP addresses are set for the IGMP Query messages sent by the device both in a super VLAN and a sub-VLAN, the configuration in the sub-VLAN takes effect preferentially.

The user VLAN inherits the relevant configuration of the multicast VLAN.

Example

# Set the source IP address to 1.1.1.1 for the IGMP Query messages sent by the device in VLAN 100.
