I would like to implement multicasting on my network. I've been reading white papers of the Cisco's website. Now I am a little confused with all that information. I've got two 5505s with RSMs at the core and then mixture of routers and switches. I would like to implement multicasting on 5505s and switches only. What would be the best protocol to use ICMP, CGMP, or ICMP snooping? Should I implement multicasing on my server farm switches?

Any information on multicasting including personal experience is more is welcome?

Thanks a lot.

Re: Multicasting

Start with IGMP on the switches, and PIM sparse-dense on the routers. There's a couple of Cisco Video on Demand (VOD) presentations about multicasting from Networkers 2001 that you may find useful.
