4000 Router Series IP Multicast Configuration Guide

• When a member of a multicast group in the SSM group range sends an IGMPv1 or IGMPv2 report

message, the device does not trigger a (*, G) join.

Configuration prerequisites

Before you configure common PIM features, complete the following tasks:

• Configure a unicast routing protocol so that all devices in the domain are interoperable at the

network layer.

• Configure PIM-DM, or PIM-SM.

Configuring a multicast data filter

In either a PIM-DM domain or a PIM-SM domain, routers can check passing-by multicast data and

determine whether to continue forwarding the multicast data based on the configured filtering rules. You

can configure a PIM router to act as a multicast data filter to help implement traffic control and control the

information available to downstream receivers.

A filter can filter not only independent multicast data but also multicast data encapsulated in register

messages. Generally, a filter nearer to the multicast source has a better filtering effect.

To configure a multicast data filter:
