Overview of IP multicasting
Multicast protocols allow a group or channel to be accessed over different networks by multiple
stations (clients) for the receipt and transmit of multicast data.
Distribution of stock quotes, video transmissions such as news services and remote classrooms,
and video conferencing are all examples of applications that use multicast routing.
BigIron RX supports two multicast routing protocols—Distance Vector Multicast Routing Protocol
(DVMRP) and Protocol-Independent Multicast (PIM) protocol along with the Internet Group
Membership Protocol (IGMP).
