Example 9-5 shows the IGMP max query response set at 10 seconds. A router must receive a membership report within the max query response time interval, or else it will prune the interface. The Last member query response interval allows for the router to check once more before pruning the interface. The Multicast groups joined shows the multicast groups that the router knows on VLAN 3.
