messages received for 'Router Port Purge Interval' time, the learned router port entry will be purged. Default
is 260 seconds.
Last Member Query Interval (1-25 sec):
The Last Member Query Interval is the Max Response Time
inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of
time between Group-Specific Query messages. This value may be adjusted to modify the "leave latency" of
the network. A reduced value results in reduced time to detect the loss of the last member of a group. Default
is 1 second.
Max Response Time (10-25 sec):
The Max Response Time specifies the maximum allowed time before
sending a responding report message. Adjusting this setting effects the "leave latency", or the time between
the moment the last host leaves a group and when the multicast server is notified that there are no more
members. It also allows adjustments for controlling the frequency of IGMP traffic on a subnet. Default is 10
seconds.
