Usage Guidelines

Usage Scenario

If IGMP messages sent from an upstream router may not reach a downstream Layer 2 device due to specific causes (for example, IGMP is not enabled on the upstream router) or the upstream router does not need to learn multicast forwarding entries dynamically because static entries are configured, the Layer 2 device can be configured as a querier to replace the upstream router to send IGMP Query messages. This reduces the burden of the upstream device. The display igmp-snooping querier command can be used to view querier configurations.

Example

The actual command output varies according to the device. The command output here is only an example.
