Configuring Multicast Migration

To configure your network to transfer both multicast and nonmulticast traffic

using multicast migration tools, follow these steps:

Make sure that IGMP is configured on the router interfaces that will be

receiving or forwarding the multicast or nonmulticast traffic.

IGMP is automatically enabled on any interface that you configure with

DVMRP or MOSPF using Site Manager. For instructions on starting IGMP on

a router interface, see “Starting IGMP” on page 2-2.

Configure an IP traffic filter if you need to convert packets from unicast

to broadcast, or from broadcast to unicast. You must also configure an IP

traffic filter to convert packet data from multicast to unicast/broadcast,

or from unicast/broadcast to multicast.

To convert packets from unicast/broadcast to multicast, a multicast protocol

must be running on the incoming interface. For instructions on how to

configure IP traffic filters, see Configuring Traffic Filters and Protocol

Prioritization.

Configure an IGMP static forwarding policy using Site Manager for the

interfaces that are static (nonmulticast) or dynamic (multicast).

For instructions, see “Configuring IGMP Static Forwarding Policies” on page

3-33.

Depending on whether the multicast protocol on your router interface is

DVMRP or MOSPF:

• See “Enabling Multicast Migration Between DVMRP and Nonmulticast

Interfaces” on page 4-32.

• See “Enabling Multicast Migration Between MOSPF and Nonmulticast

Interfaces” on page 5-8.

You may need to set policy filters to identify acceptable gateways,

interfaces, tunnels, and networks for passing traffic using IGMP,

DVMRP, and MOSPF. For example, you may need to specify an incoming

network address to which a user-defined multicast routing policy applies.
