Hi GS !
To filtering multicast stream, we have some methods:
1. ip igmp access-group {ACL}
2. ip multicast boundary {ACL} in/out
3. ip access-group {ACL}
4. ip igmp filter {profile-number}
Actually, I always confuse when choosing the method 1 & 2 & 3. With method 4,
I don't understand how it work? And which situation is used ?. In my
understand that:
- "ip igmp access-group": filter base on "inbound direction"
- "ip multicast boundary": filter base on "inbound/outboud direction"
- "ip access-group": filter base on "inbound/outbound" (this method is not
common)
- "ip igmp filter {profile} : I don't understand this method. I read on DocCD
"You can control the distribution of multicast services, such as IP/TV, based
on some type of subscription or service plan. You might also want to limit the
number of multicast groups to which a user on a switch port can belong."
Can anyone clarify 4 above methods, please. (which scenario is used for each
method)
Thanks
