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
Use this command to configure the IGMP version used on an interface.
Use the no form of this command to restore the default.
Syntax
