In fact, I have tried putting both filters together, they work independantly
very well.
My understanding, case 1: interface is connected to hosts only, then "igmp
access-group" or "ip multicast boundary out"
case 2: interface is connected to hosts and downstream routers, then "ip
multicast boundary out".
Best Regards,
