Now, by double-clicking, you got the CLI (Command Line Interface) of the router on your Terminal or Putty(A application to take CLI of various devices). In this lab, I’m just taking four Routers of the Cisco 7200 series. Now you just have to select your Network appliances present in the left-hand pane. GNS3 New ProjectĪfter, creating a new project. For this, first, open GNS3 and create your First Project.
In this section, we will create our first Network Topology, with the help of Cisco 7200 Series Routers. So far, we came to know what is GNS3 where we use GNS3.
Operating System: Windows 7, Windows 8 & Windows 10 (64 bit), Linux Distro – Debian/Ubuntu-based Linux Operating Systems (Ubuntu, Mint, Debian) & macOS Requirements to run GNS3 – The Graphical Network Simulator
Note: GNS3 is a Free and Open Source software under GPL v3 licensing!īefore downloading the GNS3 network simulator, let’s go through the minimum and recommended requirements of the system. Currently, the latest version of GNS3 is 2.2.16. However, if you want to download it from the official gns3 website, you need to signup on. Since it is an open-source simulator, so you can download it from GitHub.
But, as you already know, the GNS3 can only be available for 64 bit of Windows System. The GNS3 network simulator is completely free for all types of operating systems. So, you can easily build new topologies and learn protocols such as OSPF, EIGRP, STP, etc.
When needed, we can easily integrate the GNS3 virtual devices such as Router to the other virtualization platform, i.e VMWare, Virtual Box, etc.
So, you can able to run virtual firewalls directly on it. You will get an amazing experience of virtualization.Īnother best thing in that newer versions of GNS3 supports QCOW files, which means you can run KVM virtual machines directly on it. CCNA, CCNP, or CCIE, you defiantly try it out. In case, if you are a networking student and preparing for any of the Cisco Certifications, i.e. GNS3 also a cross-platform network simulator, so you can easily download and install in Windows, Linux, and macOS based systems. So, you can easily practice with different products to build your carrier in networking. Since it’s an open-source tool, so you can easily run different appliance belongs to different vendors.
GNS3 a Network Simulator which lets you run virtual network devices like, Routers, Switch, and Firewalls. GNS3 stands for Graphical Network Simulator.
