IGMP snooping is the process of listening to Internet Group Management Protocol ( IGMP ) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission.. In this case, You should turn off or disable IGMP Snooping and set the multicast rate to be fixed at the lowest value possible. How does IGMP Querier work? An IGMP Querier is capable of sending a periodic message (called an IGMP Membership Query) to well-known Multicast IP address 224.0. 0.1 (all multicast-capable hosts) at a specified interval. Firstly, you need to enable IGMP Snooping. On the core switch (if you have one according the above diagram), IGMP Snooping can be disabled. On the edge switches, you need to enable IGMP Snooping. An example of this setting on a Cisco SG300-52 model switch is shown below. IGMP snooping fast leave Enable Disable Enable Dynamic multicast router port Disable Disable Enable Forwarding unknown multicast Disable Disable Router port only ... The following uses Cisco SG300 as an example, but similar procedures can be applied to any L2/L3 managed switch.

This is what Cisco doc says about it: "With the no ip igmp snooping tcn flood command, you can disable multicast flooding on a switch interface following a topology change. """"Only the multicast groups that have been joined by a port are sent to that port, even during a topology change."""""""". The purpose of Cisco Group Management Protocol (CGMP) and Internet Group Management Protocol (IGMP) snooping is to restrain multicast traffic in a switched network. By default, a LAN switch floods multicast traffic within the broadcast domain, and this can consume a lot of bandwidth if many multicast servers are sending streams to the segment.
