I am trying to understand how mulitcast works and have read a few documents out there. We have a 6 servers that requires mulitcast, however we do not feel comfortable doing this on our catalyst 6509 because it's our main switch/router and the servers plug directly into this. What we were thinking of doing is adding a 2950 or 2960 to have only these 6 servers and allow multicast throughout this switch but not on the uplink, the uplink will be plugging back into the 6509. Will this work? Any help is greatly appreciated!
