Multicast Forwarding
Multicasting is a method for transmitting large amounts of information to many, but not all, computers over an
Internet. One common use is to distribute real time audio and video to the set of computers which have joined
a distributed conference.
Multicasting is similar to radio or TV broadcasts in the sense that only those who have tuned in to a particular
frequency receive the information. You see and hear the channel you are interested in, but not the others.
Since a router should not be used as a passive forwarding device, Motorola Netopia
forwarding multicasting. This protocol is Internet Group Management Protocol (IGMP). Motorola Netopia
Routers can use either IGMP Version 1, Version 2, or Version 3, however, Multicast Forwarding will only work if
your service provider supports it. Check with your service provider. IGMP forwarding is enabled per IP Profile
and WAN Connection Profile.
You configure Multicast Forwarding in two Telnet menu screens:
