Design Reference

Chapter 17: Layer 1, 2, and 3 design
examples
This chapter provides examples to help design your network. Layer 1 examples deal with the
physical network layouts. Layer 2 examples map Virtual Local Area Networks (VLAN) on top of the
physical layouts. Layer 3 examples show the routing instances that Avaya recommends to optimize
IP for network redundancy.
Layer 1 example
This section describes a Layer 1 network design example that focuses primarily on the physical
network layout. In this example, an Avaya Virtual Services Platform 4000 Series switch can function
as an access switch.
Layer 1: Design example
This example uses double physical links and distributed MultiLink Trunking (DMLT) to provide a
redundant network.
