Chapter 2: New in this release
The following sections detail what is new in the Network Design Reference for Avaya Virtual Services
Platform 4000 (NN46251–200), for release 3.1.
Features
See the following sections for information on feature-related changes.
IP multicast over SPBM
In Release 3.1, Virtual Services Platform 4000 supports IP multicast over Shortest Path
Bridging MAC (SPBM). IP multicast over SPBM greatly simplifies multicast deployment, with
no need for any multicast routing protocols such as PIM.
With IP multicast over SPBM, Avaya Virtual Services Platform 4000 supports the following:
• Layer 2 Virtual Services Network with IGMP support on the access networks for optimized
forwarding of IP multicast traffic in a bridged network (Layer 2 VSN with IP multicast over
SPBM).
• IP multicast routing support for Global Routing Table using SPBM in the core (IP Shortcuts
with IP multicast over SPBM).
• Layer 3 Virtual Services Network with VRF based IP multicast routing support over SPBM
in the core and IGMP on the access (Layer 3 VSN with IP multicast over SPBM).
For more information, see
SPBM design guidelines on page 73.
Autogenerated CFM MEP and MIP levels
Release 3.1 simplifies Connectivity Fault Management (CFM) configuration with
autogenerated CFM. With the simplified autogenerated CFM, you use the commands cfm
spbm enable and cfm cmac enable and the device creates a default MD, MA, MEPs and
MIPs.
You do not have to configure explicit MEPs and MIPs and associate multiple VLANs with MEPs
and MIPs. Now you can use the autogenerated CFM feature that creates a MEP and MIP at
a specified level for every SPBM Backbone VLAN (B-VLAN) or C-VLAN.
