Creating A Virtual Lab with GNS3 and VmWare Workstation 10 (Vid 1- GNS3Setup) Posted on Nov 13, 2013 by jay. I just demonstrate how to download and install GNS3. Content tagged with gns3, gns3setup.

Start by clicking on import appliance from the file menu in GNS3 and select the FTDv template to being the import. Once selected the import process will display a description of this appliance as well as some information on its architecture.
We were discussing about physical networking with GNS3. GNS3 is the wonderful software for virtual networking computing. Last article, we had a discussion on virtual LAN network. In this tutorial I would like to share how to configure GNS3 to connect VirtualBox virtual machines.
As we know GNS3, the best virtual network software, supports oracle VirtualBox, hence it is easy to work around VirtualBox virtual machines (VMs) as comparing to vmWare VMs. Even though we could Interface GNS3 to vmWare with some tweaks that I will cover later.
By interfacing GNS3 to connect VirtualBox you may realize the real network scenarios as a practical feel.Now, let’s see the steps for connect GNS3 to VirtualBox Virtual Machines.Before you BeginPlease make sure that you have the knowledge of the following and have equipped with specified tools and hardware.Preliminary Knowledge. Basic understanding of GNS3 virtual network simulator (Check out some of my previous ). Installing and configuring Oracle VirtualBox virtual machine. Tools required. Graphical Network Simulator GNS3: GNS3 is free Network Simulator that is available to download from the link. Cisco IOS: GNS3 works with real Cisco Internet Operating System, you need to have a Cisco IOS for setting up virtual network labs. Distributing Cisco IOS is illegal so I could not support you for that, just Google it.
Oracle VM VirtualBox: There are many Virtualization software are available, but Oracle VirtualBox is FREE and GNS3 supports it directly!My Hardware:. Intel Core i3 Windows 7 PC. 8GB RAMI recommend these hardware configurations to learn virtual networking concepts because virtual machine networking requires at least 2 VMs to be up and run.
Anyway you may also proceed even with 4GB RAM.No you are ready to go.! How to Connect Gns3 to VirtualBox VMsVMs acts as virtual network client for GNS3 network topology.The step by step procedure to connect GNS3 to VirtualBox as follows.Step 1: Setting up of VMsMake sure you installed VirtualBox VMs, for me I have 4 VMs installed. Among these I will connect Win71 and Win72 to GNS3.Step 2:Run GNS3, Edit → Preferences → VirtualBoxIn the General Settings tab click ‘ Test Settings’ button, you will see a message ‘ VBoxwrapper and VirtualBox API have successfully started’.Step 3:Select ‘ VirtualBox Guest’ tab, you may find all VMs in the VM List. Select suitable one after setting an Identifier Name. Set required VMs and the click Save button.Step 4:Browse VirtualBox guest to the work space.If you have more than one VM, you will be asked to select one among those.Step 5: GNS3 Network scenario with VirtualBoxBuild a simple scenario with VirtualBox guest.
For me, I done with two VMs and one router.Step 6: Run SimulationNow let’s run our Network. Before running the simulation open VirtualBox side by side with GNS3. Only open VirtualBox, do not run any VMs. Then click Start button to begin simulation.After starting the simulation the we can see all of the VMs that you added in the example scenario will run automatically.Step 7: Set Static IP for VMsOnce the VMs are started change the IP of virtual machines. In my example I assigned 10.0.0.2/8 and 20.0.0.2/8 to the VMsStep 8: Cisco Router Configuration for VirtualBox Interface.Now configure the router and assign IP address to each port. Configuration commands are followed. R1#configure terminalEnter configuration commands, one per line.
↓. DevenHi there, Thank you for the step-by-step guide.I am trying to connect two or more VirtualBox VMs with a cisco IOU, in a same subnet within GNS3. I can successfully ping between Cisco IOU(Layer2 switch, simulation) and the router. But I am not getting anything when trying to ping VMs. Subnet I am using is 172.240.16.0 /22Cisco router 172.240.16.1Cisco IOU(vlan 1) 172.240.16.2VM DC 172.240.16.3 (cannot ping)VMs are connected to correct vlan, which is vlan 1.When I connect one of the VMs directly to the router, bypassing Cisco IOU, I do get successful pings from both sides (router and the VM).When I omit VMs and just connect Router and Cisco IOU, I do get successful pings from both sides again.But when I put together everything connected.( Router to Cisco IOU to VMs) I just get successful pings from router and IOU, back and forth.Please assist me, thanks in advance.
