43 Configuring IP Multicast
VLAN
Multicasting is a one-to-many transmission mode. It is similar to broadcasting, except that multicasting
means sending to specific groups, whereas broadcasting implies sending to all. When sending voluminous
data, multicast saves considerable bandwidth as the bulk of the data is transmitted only once from its
source through major backbones and are distributed out at switching points closer to end users.

IP Multicast VLAN (IPMV) is an innovative feature for service providers delivering residential voice and
video services. It involves the creation of separate dedicated VLANs built specifically for multicast traffic
distribution. These distribution VLANs connect to the nearest multicast router and support multicast traf-
fic only.

In This Chapter
This chapter describes the basic components of IP Multicast VLAN and shows how to configure them
through the Command Line Interface (CLI). CLI commands are used in configuration examples; for more
details about command syntax, see the OmniSwitch CLI Reference Guide.

Note. You can also configure and monitor IPMV through WebView, Alcatel-Lucent’s embedded web-
based device management application. WebView is an interactive and easy-to-use GUI that can be
launched from OmniVista or a web browser. Please refer to WebView’s online documentation for more
