	IP MULTICAST ROUTING

This chapter describes how to set up your LANplex® system to use IP multicast routing. You should have previously defined IP interfaces and routes as described in Chapter 9: Administering IP Routing, before you define any IP multicast interfaces.

This appendix includes information on how to display or configure the following parameters:

■Enabling and disabling the Distance Vector Multicast Routing Protocol (DVMRP)

■Enabling and disabling the Internet Group Membership Protocol (IGMP)

■Administering IP multicast interfaces

■Administering multicast tunnels

■The Route display

■The Cache display

To use IP multicast routing on the LANplex system, you must have already defined one or more IP interfaces. See Chapter 9, Administering IP Routing.
