Router and Switch Multicast Configuration

This document is not a network multicast configuration guide. Refer to Configuring IP Multicast Routing for a complete implementation story. This document covers the basics to enable multicast within your network environment.

Enable IP Multicast Routing

IP multicast routing allows the Cisco IOS® software to forward multicast packets. The ip multicast−routing global configuration command is required to allow multicast to function in any multicast enabled network. The ip multicast−routing command should be enabled on all routers within your network between the WLC(s) and their respective access points.

Router(config)#ip multicast−routing

Enable PIM on an Interface

This enables the routing interface for Internet Group Management Protocol (IGMP) operation. The Protocol Independent Multicast (PIM) mode determines how the router populates its multicast routing table. The example provided here does not require the rendezvous point (RP) to be known for the multicast group and therefore sparse−dense−mode is the most desirable given the unknown nature of your multicast environment. This is not a multicast recommendation to be configured to work although the Layer 3 interface directly connected to your controller should be PIM enabled for multicast to function. All interfaces between your WLC(s) and their respective access points should be enabled.

Router(config−if)#ip pim sparse−dense−mode
