Currently we are trying to setup multicast on a LAN. An application being used allows for building multiple desktops from a server using multicasting. However multicasting isnt setup in the router or switches. so far i have enable multicasting on the router using the global command. What are the next steps. My understanding is i have to enable IGMP on the LAN interface of the router and also CGMP on the switches, is this correct? if so how do i do this. Repeating that multicast only needs to be done on the LAN not across multiple routers.
