VNX tutorial scenario using OpenvSwitch and VLANs

(To be completed)

Description  

This tutorial scenario is intended to show how to configure and use OpenvSwitch (OVS) VLAN support in a VNX scenario. It shows also how to create direct connections between OVS switches.

The scenario is made of three OVS switches connected in a line topology with six Ubuntu LXC virtual machines (VM) connected to them (two VM to each switch). Besides the host has an interface connected to Net2.

Three VLANs (1,2 and 3) are defined in the scenario, as show in the figure.
