This object sets the Last Member Query Interval, the maximum response time used in Group-Specific Queries sent after a Leave Group message and the spacing between those queries, directly affecting how quickly the router detects that a group has no more members after a leave. A lower value reduces the network's leave latency, letting the router stop forwarding multicast traffic for an abandoned group sooner. For example, an administrator managing bandwidth-sensitive video multicast might lower this interval so unused streams are torn down faster after the last viewer leaves.
