In the GNS3 application, from the menu select Control->Start/Resume all devices to start your routers, and once the routers have started, from the menu select Control->Console to all devices icon. You will be prompted with:ĭo you want to run “startup.2 (eigrp configured)”, or display its contents?” In this folder you will see several files whose name begin with startup… Find the file called startup.2 (eigrp configured) and double click on it. This will open up a folder of exercises, and from there open the exercise 3Router-ICND_Book_Example. To get to the working example, start by double-clicking the GNS3 Files-More exercises here icon. Or of course, you could just build your own network based on the diagram below. (If you are not working with the GNS3 Workbench, then download the topology, config and startup.vpc files here ).
To keep things simple, I’m going to start with the nice triangular network that is found in Wendell Odom’s CCNA books.
To get started, I’ll assume you are working with the GNS3 Workbench, and have access to some working configurations. Technical note: This tutorial was written using VPCs version 0.21 – and some of the functions described here will not work exactly the same on 0.20a, and for version 0.16 – you will have to use echo instead of TCP and UDP ping options.
Many people are not aware of how to make the best use of the features the the Virtual PCs ( VPCs) program, so I thought I’d run a small tutorial.
