Other Changes - Avaya 8800 Planning And Engineering, Network Design

the ERS 8800/8600 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 today.
This new functionality now extends the SPBM IS-IS control plane to additionally exchange IP
Multicast stream advertisement and membership information, which means that you can now use
SPBM for L2 (Unicast, Broadcast, Multicast) virtualization as well as L3 (Unicast, Multicast) routing
and forwarding virtualization.
There are three operational models supported with IP Multicast over SPBM:
1. Layer 2 Virtual Services Network with IGMP support on the access networks for optimized
forwarding of IP Multicast traffic in a bridged network (L2 VSN with Multicast)
2. IP Multicast routing support for Global Routing Table using SPB in the core and IGMP on the
access (IP Shortcuts with Multicast)
3. Layer 3 Virtual Services Network with VRF based IP Multicast routing support over SPB in
the core and IGMP on the access (L3 VSN with Multicast)
For important information on IP Multicast over SPBM, see Avaya Ethernet Routing Switch
8800/8600 Configuration — Shortest Path Bridging (NN46205–525).
