IGMP Filtering on source port

daniel.tanch · ‎03-31-2014

Hi,

I had 2 source ports from my SP which is for the IPTV streaming and the multicasting address is 229.10.10.1 - 10 & 229.10.20.1 - 10. Is there anyway I am able to do a source address filter on the incoming source port? Eg Port G1/0/23 the multicast address will be from 229.10.10.1 - 10 and Port G1/0/24 the multicast address will be from 229.10.20.1 - 10.

I try creating IGMP Profile and apply the filter on the interface but it does not work. Was wondering if there is any other methods to achieve this. Thanks in advance.

Hello,

First of all multicast address are never used as source addresses, will always be destination.

Now I can see you are attempting to allow only traffic for certain multicast address via some specific ports.

Ex:

G1/0/23 for 229.10.10.1-10

G1/0/24 for 229.10.20.1-10

Why dont' you use a multicast boundary filter?

Do you need to do it at the switch level?

If yes, please provide IGMP Profile config
