That is not true.
Multicast is a network service. It
is of type send-on-receive-anyone. That means, that one packet is send and it is
received by anyone, listening to that multicast IP/PORT.
If you have an Ethernet, than you
have the Multicast ability. Routing multicast packets is a different
question.
Having one, or more Ethernet
networks, connected with "dumb" equipment (HUBs, SWITHCHes, REPEATERs) also
gives the multicast routing.
Internet multicast routings is
somehow more complicated.
It is enough to say, that if you
have a single dumb ethernet connection between your boxes is enough for the
Orion multicast clustering to work.
Of course all the boxes have to be
configured to use one and the same Multicast IP and one and the same
PORT.
That's it.
