GNS3 Network Simulation Guide (Paperback)

From installation through to creating large scale simulations, this is the complete guide to GNS3 that will give you the know-how needed for Cisco certification. For networking professionals, it’s a career-advancing tutorial.

Overview

• Develop your knowledge for Cisco certification (CCNA, CCNP, CCIE), using GNS3
• Install GNS3 successfully on Windows, Linux, or OS X
• Work your way through easy- to- follow exercises showing you how to simulate your test network using Cisco routers, Ethernet switches, and Virtual PCs
• Expand your existing simulations by including PCs running in Qemu or VirtualBox VMs, Cisco ASAs, Juniper routers, and Vyatta routers
• Increase your networking knowledge by learning how GNS3 orchestrates multiple hypervisors, simulators, and real-world live connections

In Detail

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.
