steps, you can ensure that the IGMP host (IP is 192.168.20.168) has implemented "immediate leave"
from multicast group.
interface ethernet 0/0
ip igmp immediate-leave imme-leave
exit
ip access-list standard imme-leave

7.2.11 Configure TTL Threshold
You can use to configure TTL threshold the multicast message allowed to pass and use to apply default
value. Default value is 1.
Command
ip multicast
ttl-value
In the parameter prompt Select 17 option ，prompt is as below:
(00)access-group
......
(11)multicast
......

input 3，Select ttl-threshold option ，prompt is as below:
Please Input the code of command to be excute(0-22): 0
Select 0，and specify ttl-value.
Example of TTL Threshold configuration
The following example demonstrates how to configure TTL threshold on a port.
