You can use Media player or real player - and the statistics will show that you are using multicast or unicast. If it uses unicast then there is a problem. Now technically you cannot go to www.mediacrossing.com unless and until your network is attached to the mbone. What you need to make sure is that your upstream provider has multicast turned on - on his routers so that you are capable of receiving multicast packets. If that is not there - you cannot do multicast. 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. -V

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.

You'll need a HiPer ARC router card installed in the chassis to do multicast. The Netserver router card has no multicast capability. Multicast is disabled by default on the HiPer ARC. To turn it on you do something like:
set ip multicast proxy interface eth:1 set ip igmp eth:1 multicast_forwarding enabled set network user default igmp multicast_forwarding enabled set network user default igmp multicast_proxy enabled set network user default igmp routing enabled
This seems to work for users wishing to receive multicast via dialup. I haven't yet tested whether this also allows users to source multicast via dialup.
