Multicast Forwarding
Multicast is a method for transmitting large amounts of information to many, but not all, hosts over an Internet.
One common use is to distribute real time audio and video to the set of hosts which have joined a distributed
conference.
Multicast is similar to radio or TV broadcasts in the sense that only those who have tuned in to a par ticular
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 for warding device, Netopia routers use a protocol for for warding
multicasting. This protocol is Internet Group Management Protocol (IGMP). Two versions of IGMP are available,
V1 and V2. Netopia routers can use either one, however, Multicast For warding will only work if your ser vice
provider suppor ts it. Check with your ser vice provider.
You configure Multicast For warding in two console menu screens:
■ First, you enable Multicast For warding in the IP Setup screen in the System Configuration menu,
■ Then you associate it with a Connection Profile in the IP Profile Parameters screen in the
Add/Display/Change Connection Profile menus.
Navigate to the IP Setup screen.
