Multicast
« on: March 12, 2014, 02:59:47 PM »

Hi all,

     I have a question about a switch specification that says it has 4K Multicast routes AND 256 groups. To me this seems odd since i've always seen multicast specs given in terms of groups. So whats the difference between 4k routes and 256 groups? What am I missing?  ???

Also, I would appreciate if someone can shed light on how I can calculate exactly how many multicast groups I really need for a core switch? If I have about 10 IPTV and each IPTV can have max 4 streams. Does that mean 10*4 = 40 groups that I really need?

Thanks!
