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.

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.

Configuration procedures described in this chapter include:

• Creating and Deleting IPMVLAN on 

.

• Assigning and Deleting IPv4/IPv6 Addresses on 

.

• Assigning and Deleting a C-Tag on 

• Creating and Deleting a Sender Port on 

• Creating and Deleting a Receiver Port on 

• Associating an IPMVLAN with a Customer VLAN on 

.

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 
information on configuring and monitoring IPMV through WebView.
