Enabling IGMP Immediate-Leave
If the querier does not receive a response to a group-specic or group-and-source query, it sends another (querier robustness value). Then,
after no response, it removes the group from the outgoing interface for the subnet.
IGMP immediate leave reduces leave latency by enabling a router to immediately delete the group membership on an interface after
receiving a Leave message (it does not send any group-specic or group-and-source queries before deleting the entry).
• Congure the system for IGMP immediate leave.
