Usage Guidelines
Usage Scenario
IGMP has three versions: IGMPv1, IGMPv2, and IGMPv3. You can select a n IGMP version using this command.
Prerequisites
Multicast routing has been enabled using the multicast routing-enable command.
Precautions
You must configure the same IGMP version on all multicast devices on the same network segment to ensure that the devices work properly.
A device cannot switch between different IGMP versions automatically.
This command functions in the same way as the igmp version command used in the interface view, except for the function range. The configuration in the IGMP view is globally valid, whereas the configuration in the interface view is valid only for the current interface. The configuration in the interface view takes precedence over the configuration in the IGMP view. The configuration in the IGMP view is used only when the configuration in the interface view is not done.
