The last-member query interval is the maximum amount of time between
group-specific query messages, including those sent in response to leave-group
messages. You can configure this interval to change the amount of time it takes a
routing device to detect the loss of the last member of a group.
Query Interval
The amount of time between IGMP General Query messages sent by the router
(if the router is a querier on this subnet).
Query Response
Interval
The maximum amount of time in seconds that the IGMP router waits to receive a
response to a General Query message. The query response interval is the
Maximum Response Time field in the IGMP v2 Host Membership Query message
header. The default query response interval is 10 seconds and must be less than
the query interval.
Group Leave Delay
The amount of time in seconds that the IGMP router waits to receive a response
to a Group-Specific Query message. The last member query interval is also the
amount of time in seconds between successive Group-Specific Query messages.
