Basic GNS3 Configuration

Real World Application:

In this lab you will learn how to configure GNS3 CCNA Cisco equipment for training purposes of the loose-leaf book of basic parameters.


Actually illegal to use in the "production environment" PE se GNS3, it can, but is a great tool for the configuration verification (s) and training. In this binder is to all intents and purposes, you will be using GNS3 and fundamental in learning the ins and outs of Cisco router and switch configuration.

Lab Objectives:

In this lab, you will learn how to configure GNS3 CCNA Cisco equipment for training purposes of the basic parameters of the loose-leaf book.


Actually illegal to use in the "production environment" PE se GNS3, it can, but a great tool to configure verification (s) and training. The programming sequence is to all intents and purposes, you will be using GNS3 and learn the ins and outs of Cisco router and switch configuration.

If you wish to use other images, you will have to manually configure them in the GNSv3 topology.

Lab Instruction:

Step 1. First launch the GNS3 application for the first time and you’ll be prompted by the GNS3 Setup Wizard as shown below;

Step 2 . You need to configure and test the paths and Dynamips (router emulator engine) you can click on the button, the installation wizard prompts, you will be prompted with the following configuration window figure 1 into the working directory. Verify that the path information is correct. But if you want to use SecureCRT on Windows x64, then you will need to change the command string for the Terminal application c:\PROGRA~1\VANDYK~1\SecureCRT\SecureCRT.exe "Terminal settings" tab in GNS3 setup packages include PuTTY/T/N%d/telnet 127.0.0.1%p

Step 3 . Dynamips listed down the left hand side of the Preferences window click on the tab and verify that the path to the executable file and the working directory is correct. Once you are done, click the test button, if all configuration variables are the best button for service you can receive messages, reading; Dynamips started successfully

Loose-leaf book free CCNA Cisco GNS3 topology used and 3,725 router. Before you continue, get the images listed in the prerequisites and open using WinRAR and extract the image to \gns3\images\ to extract images

Step 4 . Can Dynamips started successfully, return to the installation of GNS3 Elves out of GNS3 preferences window. Now, the business variables are correctly configured, you will need to configure your router to use baseline configurations in GNS3. In GNS3 number 2 box, click the installation wizard to launch the IOS image and hypervisor configuration window. You need at least 128 MB RAM configuration and 3,725 platform and platform to point to the correct image is uncompressed, you are placed in \gns3\images\

Please note that the latest free CCNA Binder GNS3 topology needs, change the memory usage of hyper-visor is limited to 2048, you can by clicking on the hyper-visor Organizer tabs when you Dynamips configurations in GNS3 Preferences tab.

Step 5 . Once configured by the two platforms required stub local area network topology (shown below) you can sign out IOS and Super visor GNS3 configuration window and exit the installation wizard, and you are ready to continue to the next lab, will need to import the stub zone networking GNS3 topology configurations.
