I've read alot about IGMP snooping but I'm still not sure if the device creating the multicast traffic has to have some sort of IGMP snooping feature. I think the answer is no and that it is all handled by the network switch and routers. Can someone confirm this?
Also, I put a packet sniffer (Ethereal) on my switch and created multicast traffic on the other end of the Wan. I could see the traffic on my switch even though IGMP Snooping was configured. I have 3Com switches and Marconi switches and router on the ATM Wan. Any suggestions? Can I build my own IGMP Querier??
Thanks NH
