Objective:

Configure a small network that can perform

inter-vlan communication via ROAS method.

The router should act as the DHCP controller

for the workstation machines.

This project was performed on the EVE-NG

virtual platform, please refer to "Virtualized

High Redundancy Network" project for

EVE-NG setup documentation. The

configurations for this lab are below.
