Multicast architecture
Networks today either have inefficient bridged IP multicast networks (IGMP) or IP multicast
networks that require multiple protocols that are complex to configure and operate. IP multicast
over SPBM builds on the simplicity introduced with Avaya VENA using SPBM for the control
plane with support for bridged and routed IP multicast traffic, without the inefficiencies or
complexities that exist in other topologies today.
This functionality extends the SPBM IS-IS control plane to additionally exchange IP multicast
stream advertisement and membership information, which means that you can use SPBM for
Layer 2 (unicast, broadcast, multicast) virtualization as well as Layer 3 (unicast, multicast)
routing and forwarding virtualization.
IP multicast over SPBM supports three operational models:
