Configuring IP Multicast Multilayer Switching

This chapter describes how to configure your network to perform IP multicast Multilayer Switching

(MLS). This chapter contains these sections:

• Prerequisites

• Restrictions

• Configuring and Monitoring IP Multicast MLS

• IP Multicast MLS Configuration Examples

For a complete description of the commands in this chapter, refer to the the Cisco IOS Switching Services

Command Reference. To locate documentation of other commands that appear in this chapter, use the

command reference master index or search online.

To identify the hardware platform or software image information associated with a feature, use the

Feature Navigator on Cisco.com to search for information about the feature or refer to the software

release notes for a specific release. For more information, see the section “Identifying Supported

Platforms” in the chapter “Using Cisco IOS Software.”

Note The information in this chapter is a brief summary of the information contained in the Catalyst 5000

Series Multilayer Switching User Guide. The commands and configurations described in this guide apply

only to the devices that provide routing services. Commands and configurations for Catalyst 5000 series

switches are documented in the Catalyst 5000 Series Multilayer Switching User Guide.

Prerequisites

The following prerequisites are necessary before MLS can function:

• A VLAN interface must be configured on both the switch and the router. For information on

configuring inter-VLAN routing on the RSM or an external router, refer to the Catalyst 5000

Software Configuration Guide.

• IP multicast MLS must be configured on the switch. For procedures on this task, refer to the

“Configuring IP Multicast Routing” chapter in the Cisco IOS IP Routing Configuration Guide.
