Brocade FastIron Ethernet Switch IP Multicast Configuration Guide - Manual (Page 39)

NOTE
This example assumes that the devices are actually Brocade devices running Layer 2 Switch software.
FIGURE 1 PIM SM traffic reduction in Global Ethernet environment
The devices on the edge of the Global Ethernet cloud are configured for IGMP snooping and PIM SM
traffic snooping. Although this application uses multiple devices, the feature has the same requirements
and works the same way as it does on a single device.
Configuration notes and limitations for PIM SM snooping
• PIM SM snooping applies only to PIM SM version 2 (PIM SM V2).
• PIM SM traffic snooping is supported in the Layer 2, base Layer 3, and full Layer 3 code.
• IGMP snooping must be enabled on the device that will be running PIM SM snooping. The PIM SM
traffic snooping feature requires IGMP snooping.
