IGMP INTERFACE OPTIONAL PARAMETERS
To specify the interface parameters, enter the following commands in the Interface
Configuration Mode:
T

When a router receives an IGMP version 2 leave group message, router sends
last-member-query-count group-specific IGMP query messages at intervals of
igmp-last-member-interval milliseconds.

IGMP group specific query message. If no reports are received before the
configured last member query interval, routers assumes that no receiver is
interested in this group.

interval 2000
