ip igmp immediate-leave
In IGMP version 2, use this command to minimize the leave latency of IGMP memberships. This command is used when only one receiver host is connected to each interface. This command applies to interfaces configured for IGMP Layer-3 multicast protocols, IGMP Proxy.
To disable this feature, use the no parameter with this command.

#configure terminal
(config)#interface eth1
(config-if)#ip igmp immediate-leave group-list xyz
(config-if)#exit
(config)#access-list 34 permit 225.192.20.0 0.0.0.255
