Usage
Information
Querier normally sends some group-specific queries when a leave message is received for a group prior
to deleting a group from the membership database. There may be situations when you require immediate
deletion of a group from the membership database. This command provides a way to achieve the
immediate deletion. In addition, this command provides a way to enable immediate-leave
processing for specified groups.
ip igmp last-member-query-interval
Change the last member query interval, which is the Max Response Time inserted into Group-Specific Queries sent in response
to Leave Group messages. This interval is also the interval between Group-Specific Query messages.
