There are five or six parts to this lab; there is plenty to do but it is not difficult; perhaps a little time consuming. Unlike other labs, if you only get half the lab completed, you can get partial marks. The first part is to aquaint yourself with the Vyatta router platform by looking at the helpful video provided by Vyatta; you could prepare by watching this outside of class time. The second part is learning about Virtual LANs, which we shall use in the third part using VirtualBox to implement a particular network topology and boot the machines using the materials provided. Investigating static routing and the use of the RIP routing protocol will take up the last two parts and should take the majority of the time.

One thing worth noting in this lab is that you don’t have to do anything with IPv6. However, because IPv6 would be interesting to do, there is an optional section at the end which looks at making a similar addressing structure and using RIPng.

For this lab, and particularly the following lab on subnetting and firewalls, you may well prefer to work in pairs. Take turn about configuring the machine, and doing the research as to which commands you will need. I strongly suggest you to keep the topology map for this lab within sight at all times.

On your workstations, you should find that the Live CD images, as *.iso files, for Vyatta and Ubuntu should be available from the class resource server, along with all the documentation you might need. As far as the Vyatta documentation is concerned, you should find available an electronic copy of the Vyatta Command Reference and Quickstart Guide.

1. Watch Vyatta Demonstration Video

Start this section by navigating to the Vyatta website, and viewing the video An Introduction to Vyatta. You can find this under the Products > Online Demos section of the website. This is approximately 12 minutes, and will give you some useful background information about Vyatta and the product. It is somewhat a marketing promotion, but does give you an idea of what it can do, and how the basic interface works; some of the middle can be skipped initially.
