Gns3 Junos
First of all let me provide some useful links: Olive reloaded or how to emulate Juniper routers - is about installing Junos using Qemu. Please read carefully as it. Mar 23, 2014 How to install Juniper JunOS Olive 12.1R1.9 for GNS3 with VirtualBox/VMware Workstation - Duration: 7:53. RCT vids 57,039 views.
Wait a minute! I don't quite get it: in GNS3 there is a special device type called 'Juniper Router' and as far as I can conclude from all these tutorials they only deal with qemu directly which results in a lot of routine work and somewhat unclear integration with dynamips units. What is then that mysterious 'Juniper Router' type used for?
Can one just supply JUNOS image, FreeBDS image (if necessary) and simply place the box in the network diagram all within one PC, link to Cisco virtual boxes and be happy with that? Can one just supply JUNOS image, FreeBDS image (if necessary) and simply place the box in the network diagram all within one PC, link to Cisco virtual boxes and be happy with that? It is as it works now. For doing this you need to create and run multiple virtual machines - qemu images. Each qemu image (VM) contains FreeBSD with JunOS installed. That is why we need to use Qemu if we want to run multiple Juniper routers on one PC - virtualization is needed.
Another possibility is using VMware for running multiple VMware images with FreeBSD and JunOS installed but VMware is not integrated in GNS3. If you want to use VMware, you need to connect Junipers to Cisco emulated router via cloud (loopaback or tap interfaces). As I said Qemu is integrated in GNS3 - it means you can control (create/start/stop/delete) your Qemu Junos images directly form GNS3 desktop - no need for doing this from cli. Everything what you need is to create your base-image ( and set Qemu and JunOS parameters (path to base image, type of interfaces, RAM, Qemu acceleration). You do it only once. After that you can drag and drop Juniper routers to GNS3 desktop, start routers and qemu (qemu-img), controlled by qemuwrapper create, start Juniper for you. If you don't like virtualization and you have many old computers you can install FreeBSD and JunOS on these computers and connected them via Ethernet cards.
It will works too.
In the previous posts, we have explained a lot, how to use GNS3 to perform Cisco hands-on lab exercises. Along with Cisco, nowadays Juniper also getting popularity in the routing platform. However, Juniper has its own internetworking operating system (IOS) called JunOS. It is based on Linux/Unix platform.
In order to perform the hands-on lab exercises in GNS3 that require Juniper routers, you need to add Juniper router IOS images in GNS3. Before you could add a Juniper router in GNS3, first, you need to download and on your local system. Alternatively, you can also use.

However, in this guide, we will use Oracle VirtualBox. Once you have downloaded and installed your virtualization software, next, download the JunOS Olive VM image. You can download it from the various sources on the Internet, or you may use the following link to download the JunOS VM image file.
Adding Juniper IOS (JunOS) in GNS3. Once you have downloaded the JunOS VM image, next, open the Oracle VirtualBox console. Click File and select Import Appliance to import an existing VM. On the Import Virtual Appliance window, click the Browse icon, navigate to the location where you have downloaded the JunOS image file, select it, and then click Next.
Junos Gns3 Configuration
On the Appliance settings page, accept the default resource values or adjust them as per your requirement, and then click Import as shown in the following figure. The importing process will begin. It may take 10-15 minutes. Wait until it completes. Once the VM is imported, select it and click Start to power on. If the following error occurs, click Change Network Settings. If the following error does not occur, skip the next step (step 6) and move on the GNS3 console.

On the JunOS Olive – Settings window, make sure that Microsoft KM-TEST Loopback Adapter is selected, and then click OK. We assume that you have already on your system. Now, the VM will start. Leave the VM VirtualBox console active and switch to GNS3 console. On the GNS3 console, click Edit, and select Preferences. On the Preferences window, select VirtualBox VMs in the left pane, and then select New in the right pane. On the VirtualBox Virtual Machine page, ensure that JunOS Olive VM (Juniper router IOS image) is selected. If not, select manually and click Finish and close the Preferences window. In the GNS3 console, drag JunOS Olive router in the work view area. Right-click JunOS Olive and select Configure to configure it.
On the Node Properties dialog box, select the Network tab, and set the number of adapters as per your requirement. Select the Allow GNS3 to use any configured VirtualBox adapter check box and click OK. Switch to the JunOS VirtualBox console. At the login prompt, type root as username and press Enter. The Password is blank. At the next prompt, type cli and press Enter. In the following example, root is the username and JunOS% is the hostname.
In the preceding figure, you can see that you have the JunOS console where you can execute JunOS commands that are used to configure Juniper routers. That’s all you need to do to add Juniper router in GNS3.
You can add as many Juniper routers as you wish depending on your local system resource’s capacity. Hope, it will help you to begin the Juniper hands-on exercises. Please like and share if you find it helpful. You may also subscribe us to get daily new post updates.
