Changing the IGMP Query Timeout for IGMPv2 (CLI)
If you are using IGMPv2, you can specify the period of time before the device takes over as the querier for
the interface. By default, the device waits twice the query interval period controlled by the ip igmp
query-interval interface configuration command. After that time, if the device has received no queries, it
becomes the querier.
This procedure is optional.
