robustness variable is used in calculating the following MLD message intervals:
Group listener interval - Amount of time that must pass before a multicast router
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.
