CCNA is a very prestigious certification and can land you up in a very good job.But sometimes the only thing which stop people is the cost of hardware. Buying expensive hardware for practicing cisco ccna labs is not possible by everyone . You need to spend $1000 or more for a decent lab .

The solution to this is Using GNS3 and Dynamips. Which lets you simulate routers and switches on your pc. The advantage of this simulator is that it uses real cisco ios , its not like any other simulator which are flash programmed and can run only certain commands.The gns3 can simulate layer 3 devices(Routers) very well but gets buggy sometimes with the layer 2 devices like the switches.

So lets gets started with the step by step on How To Use And Configure GNS3 And Dynamips

  1. You need to download gns3 first you can download it from gns3.net you can download it directly from here .
  2. The installation is just step by step like a normal windows installation (It can be installed on ubuntu directly from the repository) Type
    sudo apt-get update
    sudo apt-get install gns3

  3. now as the installation is complete you will see the gns 3 screen.
    Note:- GNS3 does not provide IOS you need to get it yourself.

  4. The main thing while using gns3 is idle pc value and the hypervisor configuration.
