GNS3 1.5.2 GNS3 for Mac is a software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.The components of GNS3 are the two of below: 1-The GNS3-all-in-one software (GUI).2-(Recommended) The GNS3 virtual machine (VM).Graphical User Interface: As we mentioned, GNS3 can run a small topology.This is the client part of GNS3. When you install the all-in-one software on your local PC like Windows, MAC, and Linux, you can create your topologies.Real-time network simulation for pre-deployment testing without the need for network hardwareGNS3 for Mac OS X is a graphical network simulator that allows you to design complex network topologies. You may run simulations or configure devices ranging from simple workstations to powerful Cisco routers. It is based on Dynamips, Run the OS that emulates real behavior of network hardware.Test 20+ different network vendors in risk-free virtual environmentQuickly run and test multiple hardware vendors without the need for hardware.Create dynamic network maps for troubleshooting and proof of concept (POC) testingTest your networks before you build them to reduce the time it takes to get a production network up and running.Leverage your existing hardware and expand your current lab by connecting your GNS3 topologies directly to it.Customized topologies and labs within GNS3 for network certification trainingGNS 3 is the best study tool for aspiring network professional seeking their certifications, without the need for a home lab.(But the instructor has not tested it.) Step 2: Install GNS3Note: Install GNS3 inside your native operating system. It does not come with support for the VIX API, which allows programs (like the GNS3 network simulator) to control the operation of virtual machines.VirtualBox is supported by GNS3. Normally these are paid ($$) commercial products, but SOECS has free licenses for Pacific students.Do not use the stripped-down free VMware Player. - For your reference, detailed installation document for all platforms is available on the GNS3 website, as the process does vary somewhat between platforms:Install VMware Fusion (Mac) or VMware Workstation (Windows). GNS3 allows you to run a small topology consisting of only a few devices on your laptop, to those that have many devices hosted on multiple servers or even hosted in the cloud. GNS3 is used by network engineers to emulate, configure, test and troubleshoot virtual and real networks.(If prompted, permit ubridge to run as root to capture packets)After installing the base GNS3 program, you next need to install the “GNS3 VM”. Run the installer you downloaded and accept the default options. Create your GNS3 Community Account as prompted, login, and then return to the Download page Select Windows, Mac, or Linux as appropriate, and then “Download" We'll use Ubuntu for class projects and homework assignments.
Gns3 Software That SimulateAccept the default location and accept the default name it offers ("GNS3 VM") since that will simplify locating it later. Let VMware import it as a new VM. Ovf file ("GNS3 VM.ovf") that you just downloaded and unzipped Select “Import” (or “Open a Virtual Machine”) and navigate to the. Select the image for “VMware Workstation and Fusion" This is why VMware was needed as the first installation step - it will be doing some of the virtualization heavy lifting. The default server path, binding, and port are fine here Next, enter the GNS3 local server settings Run appliances in a virtual machine <- Choose this option Next, choose how to run your GNS3 network simulations. Say YES, that will allow us to connect GNS3 with the real network if we desire. Note: You can change these settings at any time by locating the “Setup Wizard” from the application menus.Step 5: Install Mikrotik Router into GNS3Out of the box, GNS3 doesn’t come with any routers, just a very basic switch, hub, and a stripped down “computer” suitable for basic network connectivity tests. Complete the setup wizard. This is thanks to the VIX API that allows GNS3 to control VMware. VMware should be automatically launched now, and start running the GNS 3 VM by itself. One CPU core and 2048MB of RAM should be sufficient to accommodate all the virtual routers we might want to simulate at any given time. As a bonus, unlike certain other vendors (cough Cisco cough), their OS images are freely available and easy to download. So, rather than working with a facsimile of a router, you can interact with the real router software.Let's configure GNS3 with the image of a real router from MikroTik, which is the same vendor as the routers that are in the networking lab in CTC 214. As in, you can give GNS3 the same binary image you'd load on the real router, and (with proper configuration.) it will "just work". That’s the download link you want. Look at the column labeled “Stable”, and go down to the row labeled “Raw disk image”. That’s just their marketing term for a software router (Linux + their proprietary command line interface) that could run on any old PC that has a couple of network cards in it. Choose your console type - “Telnet” - and click Finish Select the amount of RAM for your router OS - 256MB is sufficient here, and given that we will eventually want multiple routers, it’s best not to pick too large of a number Enter a name for your image - “Mikrotik 6.47.1” is a helpful and obvious name - and click Next Select “Run this Qemu VM on the GNS3 VM" Select “New” to create a new Qemu VM template Locate the QEMU section in the panel window, and under it, the section labeled “Qemu VMs" Download a movie for free on macYour template is now created, but there’s a few subtle but important network settings to change. Allow GNS3 to copy it to the default images directory, and click Next. Img file you downloaded previously. GNS3 numbers its ports starting from 0, but Mikrotik numbers its ports starting at 1. Finally, fix an annoying display issue. Change the Name format from “Ethernet” to “Ether” to match the router CLI syntax. No point in having a router with a single network interface! Click “Edit", select the “Network” tab, and change the 1 to a 4. Change it to have 4 adaptors. Currently it says 1 adapter (Ethernet) of type e1000. Create a “New Blank Project” and call it lab01. That VM contains all the necessary software and settings to virtualize this router.Now you have a router that can be added to your network! Step 6: First Network Select “Ok” to edit the Preferences panel entirely.Behind the scenes, GNS3 will copy the disk image for the Mikrotik router into the GNS VM (in VMware) that you installed previously. The ports you plug your network wires into must be consistent with the way you configure your router in software. Note: The Router has 4 interfaces. Note: The PCs only have 1 interface, so you can’t connect the wire to the wrong port there Using the “Add a link” button on the left panel, wire up the network using virtual Ethernet cables! Make your network look like the network below. Drag a “Mikrotik 6.x” router onto the network diagram from the panel at left (found under the “Browse Routers” button) If prompted to "Choose a server", select "GNS3 VM". Press the Console Connect to All Nodes button to pull up a terminal to all three devices. All the links should turn from RED to GREEN. Press the Start button to launch your two virtual PCs and router. Note: Wondering why your diagram doesn’t show port labels? Press the “Show/Hide Interface Labels” button.Lab 1 Network Diagram (Note: Subnet labels and dashed borders are for informational use only) In future labs, when you’re more comfortable, you can make port decisions on your own. Select N when prompted to view the license file. Enter the default Mikrotik login of admin with a blank password. Note: We are configuring the router first, because we can’t configure the PC network fully until the default gateway (the router) exists. This sets up a subnet of 10.11.12/24, assigns the PC the IP address 10.11. Configure an IP address: ip 10.11.12.1/24 10.11.12.254 Show the help menu for available command (recall that this is a rudimentary simulated PC): help Print the configuration to confirm: ip address print ip address add address=20.30.40.254/24 interface=ether2 ip address add address=10.11.12.254/24 interface=ether1
