Command Usage
A multicast client sends an IGMP leave message when it leaves a group. The
router then checks to see if this was the last host in the group by sending an
IGMP query and starting a timer based on this command. If no reports are
received before the timer expires, the group is deleted.
This value may be tuned to modify the leave latency of the network. A reduced
value results in reduced time to detect the loss of the last member of a group.
Example
The following shows how to configure the maximum response time to 10 seconds:
ip igmp version
