Interval in seconds in which a multicast-capable router (or a simulated querier) sends IGMP queries to the multicast address 224.0.0.1, so prompting the stations to transmit return messages about multicast group memberships. These regular queries influence the time in which memberships "age", expire, and are then deleted.
After the startup phase, the querier sends IGMP queries in this interval.
A querier returns to the querier status after a time equal to "Robustness*Query-Interval+(Query-Response-Interval/2)".
A port loses its router-port status after a time equal to "Robustness*Query-Interval+(Query-Response-Interval/2)".
Note: The query interval must be greater than the query response interval.
