5.4.3 Configuring IGMP Timers

The IGMP querier periodically sends IGMP general queries to decide whether any
multicast group member exists on the network. You can tune the IGMP general query
interval based on actual condition of the network.
Upon receiving an IGMP query (general query or group-specific query), a host starts a
delay timer for each multicast group it has joined. This timer is initialized to a random
value in the range of 0 to the maximum response time, which is derived from the Max
Response Time field in the IGMP query. When the timer value comes down to 0, the
host sends an IGMP report to the corresponding multicast group.
