GNS3 Network Simulation Guide

Overview of this book

GNS3 is an open-source Graphical Network Simulator used extensively by networking professionals to simulate networking devices such as Cisco, Juniper and Vyatta routers, along with Virtual PCs. GNS3 Network Simulation Guide gives you all the information you need to run a successful GNS3 simulation. You will be guided through the tricky installation pre-requisites and procedures involved in developing a simulated topology suitable for studying for Cisco CCIE Certification. We will also cover many useful tips and tricks which will help you make the most of your GNS3 simulator application. You will begin the GNS3 journey by ensuring that you have prepared your computer with any additional files required by GNS3, to set up the simulated environment needed for a successful installation process. Once GNS3 is installed, you will get to work creating a successful simulation including routers, Ethernet switches, Virtual PCs, and capture packets using Wireshark. Next, you will learn how to master GNS3's Graphical User Interface as well as the Command Console. The inner workings of GNS3 are described in depth so that you gain an appreciation of how UDP tunnels are used to tie the many components of GNS3 together. By following the clear examples and exercises in this guide, you will learn everything that you need to know about how to use GNS3 to prepare for certifications, as well as simulate real-world network scenarios.

Getting more help


I am sure you will come across other problems that you will need to solve that I haven't been able to cover in this book. Here are a few places where you can look for help by including, for example site: forum.gns3.net, as part of your search criteria when you go looking for help.

Official websites for all the GNS3 suite of programs

The official websites for GNS3, Dynamips, Dynagen, VirtualBox, Qemu, and VPCS are shown in the following table. However, for GNS3 related information, the best starting place is the GNS3 forum, and the best way to search the forum is sadly not using the search function on the forum website, but by including the words site:forum.gns3.net, as part of your search criteria in a Google search.

If you cannot find an answer, then by all means post a question on the forum, but you might want to read http://forum.gns3.net/topic3178.html before posting to ensure you get a more positive response.
