we have multicast on our network, and thru our providers, that part is all working. Whats wierd, is I dialed into an ARC that I did not enable multicast on, and still got "multicast" in media player to mediacrossing.com..........this is accross my sparse-mode network!
Sparce-mode will work but for most part has issues, thus use dense mode. If you have Ripv2 enabled on the ARC - you do have the multicast enabled - thus you will seee multicast packets - however to make it work in our network I had to configure the default user and the ethernet interface for igmp.
We had to contact our provider and ask them to enable multicast on their routers, once that is done, the ARC forwards the packets without any problems. Your edge router and all the core routers in the path should have PIM dense mode.
Do you have a test to see if it is all done right?
The easy way to test it - Have a realstreamer on the other side of your edge router, and try to attach to it or vice versa.
We have a realvideo server. So your saying I should just try to get a stream and if it *can* use multicast then realplayer will try that first and show it is using multicast?

IGMP address on the Hiper arc. I think the command is set ip_source_address igmp <ip address of the interface>
when you say "multicast igmp address" what address is that exactly? Is that to point at my border router? Or is that a unique address to assign the arc?..........sorry i am a bit confused.
