I am trying to wrap my head around multicast design as I need to put something together like this:
I will have a group of servers that will all talk to each other via a multicast group address. (probably will choose something in 184.108.40.206/8 space) These will all be Unix boxes that have an application that will listen and send to this group...
My question is at the router side. ( cisco 6500) what do I need to do to make this work. Can i create a layer 3 vlan and enable PIM sparse for this interface so that it can forward the traffic. This would include igmp as well?
Or can you not enable all of that and it will still work. My confusion is that since the all hosts 220.127.116.11 works without any mutlicast config at the router as well as other multicast stuff, it would seem that you dont have to do that.
I do want to control the traffic properly and dont want these packets going everywhere, Can anyone give me an idea of how this would/should work and what would be the best way to do this..... Also what is best way to control this sperate group that I will use.
