ip igmp immediate-leave

Description
With this command, you enable die function "Immediate Leave" on an interface. if the
function "Immediate Leave" is enabled,, the multicast router deletes a multicast group as
soon as it receives a Leave message from the last logged-on client. The multicast router
does not query whether a further client wants to receive the multicast.
Use this function on IGMPv1 and IGMPv2 interfaces with only one client or on IGMPv3
interfaces on which the "Explicit Tracking" function is enabled.
With IGMPv1 and IGMPv2 only one client responds with a Join message to a query of the
multicast router. All other clients that want to receive the same multicast suppress their Join
message. The multicast router therefore does not know how many clients are logged on and
how many Leave messages it needs to receive before it can delete the multicast group.
Requirement
You are in the Interface Configuration mode of VLAN.
The command prompt is as follows:
cli(config-if-vlan-$$$)#
Syntax
Call the command without parameter assignment:
ip igmp immediate-leave
Result
Die "Immediate Leave" function is enabled on the interface.
