IP MULTICAST

This chapter provides guidelines and other key information about how to configure and manage IP multicast routing commands from the Administration Console of the CoreBuilder® 3500 and CoreBuilder 9000 Layer 3 switching modules.

For the CoreBuilder 9000 platform, the commands in this chapter apply to Layer 3 switching modules only.

For more information about IP multicast technology, concepts, and implementation procedures, see the Implementation Guide for your system.

For IGMP commands in Layer 2 switching systems (CoreBuilder 9400, CoreBuilder 9000 Layer 2 switching modules, SuperStack® II Switch 3900, and SuperStack II Switch 9300), see Chapter 9.
