I copied the below from cisco configuration guide:
ip access-list extended test5
deny igmp host 10.4.4.4 host
permit igmp any
ip igmp access-group test5
While the command is understood but where exactly is it going to be applied? Is it on the multicast source interface or on the igmp join group interface.
Furthermore, if I want to ensure the some group of multicast ONLY is available in a network let say 220.127.116.11 and 18.104.22.168 how and where will the acl and igmp access-group apply.
Thanks for your usual help.
