![]() For example, different routers, Ethernet switch, ATM bridge, ATM switch, frame relay switch, cloud, Qemu and VirtualBox guests will appear after clicking on the specific node symbol. Clicking onto any node symbol will provide you with the list of various types of that node. Different types of network nodes are available at the leftmost pane. The user-friendly GUI window is divided into four panes and provides you with all the options to create network topologies at the very first sight. SVG technology (scalable vector graphics) in its GUI provides high-quality symbols for designing your network topologies. While GNS3 is developed in Python, its GUI is made with the powerful Qt library. You can click and drag different routers to your screen, hit a start button and start learning and testing. GNS3 runs on top of these emulators to create a more user-friendly and graphical environment. For instance, using network emulators such as Dynagen or Dynamips independently will require you to build your labs using configuration files, but using a graphical tool like GNS3 makes things a bit easier for you. GNS3 serves as a graphical front-end for the network emulators. The GNS3 software provides an intuitive graphical user interface (GUI) to design and configure virtual networks running on traditional PC hardware for multiple operating systems, including Windows, Linux and MacOS. GNS3 integrates all the emulation and allows you to work in a real lab environment to have your host talking to your routers.īetter graphical front-end for ease of use Other emulation programs, namely Qemu, Pemu and VirtualBox, are used to emulate Cisco ASA and PIX firewalls, Cisco IPS, Juniper routers as well as hosts (Linux, Windows, MacOS X and FreeBSD). Dynamips is the core program that allows IOS emulation. It uses the Dynamips, Pemu/Qemu and Dynagen emulators to run the very same operating systems as in real networks, ensuring complete and accurate simulations. Integrated solution for network emulation It allows you to run many virtual hosts with operating systems such as Linux, Windows, MacOS X or FreeBSD. If you want to design and test your automation system network, GNS3 can just work fine for you. You can design and configure virtual networks on a traditional PC or a Raspberry Pi, and simulate in the closest possible way to how the real networks perform. With this tool you do not need to have dedicated network hardware devices. GNS3 is a graphical network simulator which provides you a real lab environment for learning and testing complex networks. Read this article to know what it does Pankaj V. Use this open source and free tool to design and test your own network with various network hardware devices and hosts, all on your Raspberry Pi. The program runs based on the hardware performance of your computer.Here is a cool tool for learning and testing in a simulated environment.You need to manually add the Router/Switch images you download.(You can download it from and purchase a VIRL license). IOS images are downloaded by the user.Large and active community (more than 800,000 members).No need for additional virtualization software.( Virtualbox, VMware Workstation, VMware Player, ESXi, Fusion). Supports both free and paid hypervisors.Supports all VIRL IOS images (IOSv, IOSvL2, IOS-XRv, CSR1000v, NX-OSv, ASAv). ![]() Supports multiple switching options (ESW16 Etherswitch, IOU / IOL Layer 2 images, VIRL IOSvL2):.There is no limit to the number of supported devices (only the limitation is your hardware: CPU and memory).AdvantagesĪfter making the GNS3 definition, let’s examine what the advantages are. ![]() IOU Devices → A real Layer2 and Layer3 Switch lets you use all the features of your network device by adding an IOS image. VirtualBox VMS → VirtualBox Virtual Machines → Including virtual machines in topology with VirtualBox. VMware VMS → VMware Virtual Machines → Including virtual machines in topology with VMware Workstation. GNS3 → GUI (Graphical User Interface) Dynamips → Emulator for IOS Dynagen → Beginning Front End for Dynamips Pemu → Cisco PIX Firewall Emulator Based on Qemu (Win)Pcap → Packet Capture Library (Driver for Sniffer) Wireshark (Old Name: Ethereal) → Network Monitoring / Listening to Network VPCS → Virtual PCs (Virtual Computer) → Adding a virtual computer. You can set the Idle-PC value when adding a device to the program. This simulator software uses IDLE-PC Value to show better performance of Cisco Routers or Switch IOS and shows you the optimal value with * character.
