Chapter 12: 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 Avaya Virtual Services Platform 4000 Configuration —
IP Multicast Routing Protocols, NN46251-504.
For design guidelines on IP Multicast over SPBM, see
SPBM design guidelines on page 73.
For more conceptual and configuration information on IP Multicast over SPBM, see Configuring Avaya
VENA Fabric Connect on Avaya Virtual Services Platform 4000, NN46251-510.
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)
Multicast and MultiLink Trunking considerations
Multicast traffic distribution is important because the bandwidth requirements can be
substantial when a large number of streams are employed. Virtual Services Platform 4000 can
distribute IP multicast streams over links of a multilink trunk using one of the methods in this
section.
