Query Interval(s):The query interval is the amount of time in seconds
between IGMP General Query messages sent by the router (if the router
is the querier on this subnet)
Query Response Interval (1/10s): The query response interval is 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

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.

susceptible the subnet is to lost packets. IGMP can recover from
robustness variable minus 1 lost IGMP packets.
