decides there are no more listeners of a group on a network.
Other Querier present interval - Amount of time that must pass before a multicast
router decides that there is no longer another multicast router that is the Querier.
Last listener query count - Number of group-specific queries sent before the router
assumes there are no local listeners of a group. The default number is the value of
the robustness variable.
By default, the robustness variable is set to 2. You might want to increase this value
if you expect a subnet to be loosely.
The maximum amount of time between group-specific query messages, including
those sent in response to done-group messages. You might lower this interval to
reduce the amount of time it takes a router to detect the loss of the last listener of a
group.
Here the user can enter the data driven group expiry time value.
