More resources allow for larger simulation Processor: 2 or more Logical cores – AMD-V / RVI Series or Intel VT-X / EPT – virtualization extensions present and enabled in the BIOS.
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.
In GNS3, you have a facility called, u-bridge, which can be used to connect any GNS3 appliance with other virtualization applications such as VMWare Workstation and Virtual Box. GNS3 supports virtual routers and switches in the IOU (IOS on Unix) and IOS (Internetworking Operating System) formats. However, to use different virtual products (i.e., Cisco/Juniper Routers, Switches, Firewalls) on GNS3, you just need to get a binary image of the devices. By default, you will get some pre-defined device templates. The GUI of the GNS3 network simulator is straightforward to use. Palo Alto, Cisco ASA, FortiGate within the GNS3. 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. Once you are logged in you will find the configuration files right here.GNS3 also a cross-platform network simulator, so you can easily download and install in Windows, Linux, and macOS based systems. You need to register to download the GNS3 topology file.
