Chapter 15: IP multicast network design
Use multicast routing protocols to efficiently distribute a single data source among multiple users in
the network. This section provides information about how to design networks that support IP
multicast routing.
For more information about multicast routing, see Configuring IP Multicast Routing Protocols on
Avaya Virtual Services Platform 4000 Series , NN46251-504.
For design guidelines on IP Multicast over Fabric Connect, see
SPBM design guidelines on
page 93.

Multicast and VRF-Lite
You can configure multicast routing support with the Virtual Routing and Forwarding (VRF) Lite
feature. This feature is known as multicast virtualization.
Multicast virtualization enables multiple VRF routing instances on devices and supports various
unicast routing protocols so that you can provide the services of many virtual routers from one
physical device.
VRF-Lite configurations support IGMP.
Multicast virtualization provides support for:
Virtualization of control and data plane
Multicast routing table managers (MRTM)
Virtualized IGMPv1, v2, and v3
Support for overlapping multicast address spaces
Support for the Global Router (VRF0)
