Last Member Query
Interval
The last member query interval is the amount of time in seconds that the IGMP
router waits to receive a response to a Group-Specific Query message. The last
member query interval is also the amount of time in seconds between successive
Group-Specific Query messages. You can also click the scroll arrows to select a
new setting.
Range: 1-25 seconds;
Default: 1
•
Robustness Variable
The IGMP robustness variable provides fine-tuning to allow for expected packet
loss on a subnet. The robust count automatically changes certain IGMP message
intervals for IGMPv2 and IGMPv3. Increasing the robust count allows for more
packet loss but increases the leave latency of the subnetwork.
Range: 1-255;
Default: 2
