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:
Console(config-if)#ip igmp last-memb-query-interval 10
Console(config-if)#
ip igmp version
