Multicast Route Overview

 

Multicast routing environments require the following items:

  • A mechanism between hosts and routers to communicate group membership information. Security devices support the Internet Group Management Protocol (IGMP) versions 1, 2, and 3.

  • A multicast routing protocol to populate the multicast route table and forward multicast traffic to hosts throughout the network. Security devices support the Protocol Independent Multicast-Sparse Mode (PIM-SM) protocol. Alternatively, you can use IGMP proxy to transmit multicast information between routers without the CPU overhead of a multicast routing protocol

    Note

    Multicast routing is only supported in ScreenOS 5.1 and later.

This topic describes the basic steps to configure the following multicast protocols:
