Multicast Routing

Configuration

Guide

IP Multicast Overview

Multicast routing on the SSR is supported through DVMRP and IGMP. IGMP is used to

determine host membership on directly attached subnets. DVMRP is used to determine

forwarding of multicast traffic between SSRs.

This chapter:

• Provides an overview of the SSR’s implementation of the Internet Group Management

Protocol (IGMP)

• Provides an overview of the SSR’s implementation of the Distance Vector Multicast

Routing Protocol (DVMRP)

• Discusses configuring DVMRP routing on the SSR

• Discusses configuring IGMP on the SSR

IGMP Overview

The SSR supports IGMP Version 2.0 as defined in RFC 2236. IGMP is run on a per-IP

interface basis. An IP interface can be configured to run just IGMP and not DVMRP. Since

multiple physical ports (VLANs) can be configured with the same IP interface on the SSR,

IGMP keeps track of multicast host members on a per-port basis. Ports belonging to an IP

VLAN without any IGMP membership will not be forwarded any multicast traffic.
