Configuring IP Multicast Protocols
Table 126 lists the individual Dell PowerConnect switches and the IP multicast features they
support. These features are supported in the full Layer 3 software image only.
This chapter describes how to configure Layer 3 Switches for Protocol Independent Multicast (PIM).
NOTE
Each multicast protocol uses IGMP. IGMP is automatically enabled on an interface when you
configure PIM or DVMRP and is disabled on the interface if you disable PIM or DVMRP.
NOTE
This chapter applies only to IP multicast routing. To configure Layer 2 multicast features, refer to
Chapter 22, “Configuring IP Multicast Traffic Reduction for PowerConnect B-Series FCX Switches”.
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.
