Hi there,
I have short question concerning Multicast in my LAN. My internet router acts as an IGMP Proxy for the LAN and distributes IPTV there. The router is connected to one of my three SG 300 10 Cisco switches (connected to one another via uplink port). Now I want all switches to send multicast traffic to only the recipients of such traffic (PCs with VLC and Network Media Players) connected to either one of them. How do I have to configure the switches to do so and not flood the LAN with multicast traffic, is it enough to enable IGMP Snooping on each switch?
Thanks in advance and best regards
Christoph

Hi Christopher, by the default the switch will treat multicast traffic like a broadcast until you enable the Bridge Multicast Filter and IGMP snooping.
Navigate to; Multicast -> Properties and enable the Bridge Multicast Filtering
Navigate IGMP snooping -> Enable
Multicast -> Multicast Router Port
Then make sure to specify the mrouter port (which must be a member of a static vlan, not a dynamic vlan)
