Chapter 15: Layer 1, 2, and 3 design
examples
This section 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, a VSP 4000 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.
