Query Interval
The interval at which the multicast router sends a query messages to hosts,
expressed in seconds.
If you enter a number below 128, the value is used directly. If you enter a number
128, it is interpreted as an exponent and mantissa.
Query Response Interval Upon receiving a query packet, a host begins counting down seconds, from a ran-
dom number. When the timer expires, the host sends its report.
Enter the maximum number of seconds that a host can pick to count down from.
The value must be greater than the
Query Interval
. If using IGMP v1, this value is
fixed at
10
seconds.
Last Member Query Inter-
val
Enter the maximum response time within which the host must respond to the Out
of Sequence query from the router. The default is
1000ms
.
IGMP uses this value when the router receives an IGMPv2 Leave report indicating
at least one host wants to leave the group. Upon receiving the Leave report, the
router verifies whether the interface is configured for IGMP Immediate Leave. If
not, the router sends the out-of-sequence query.

the more robust the query. Options are:
