6-8
IV. The maximum query time of IGMP packets
When the host receives a query message, it will set a timer for each of its multicast
groups. The timer value is selected from 0 to the maximum response time at random.
When the value of a timer decreases to 0, the host will send the membership
information of the multicast group.
By configuring reasonable maximum response time, you can enable the host to
respond to the query information quickly and enable the Layer 3 switch to understand
the membership information of multicast groups quickly.
