Junos OS gives you the tools to sanity check and compare the changes that you are about to make. Set interfaces em0 unit 0 family inet address 10.0.0.1/30 The next command is the command to assign Junos 1 it’s IP address on em0 Root# set system root-authentication plain-text-password
You will need to set a root password otherwise you will not be able make any configuration changes. NOTE Make sure that the KVM support in the GNS3-VM is available/TRUE.
The IP address of the GNS3 VM will be displayed. In order to accomplish any configuration you will need to enter into configuration mode by typing “configure”. Step 6: Power on the GNS3 VM and click open console. In this example I have used a /30 address. This will need to be in the same the subnet otherwise they will not be able to ping each other. You will need to configure an IP address on both devices. After a successful installation, shutdown the VM with the poweroff command. Install VyOS as normal (that is, using the install image command).
It will ask for the login credentials, you are at the VyOS live system. Configure a point to point link between the two devices. The console should show the system booting. Other commands which give you more detail are: Show interfaces terse command – this summarises all the connected interfaces of the device. To get your bearing of what interfaces are connected It is a good idea to run the Mode, you enter commands to monitor and troubleshoot the Junos OS, devices, and This mode displays the current status of the device. You will need to enter the word cli in order to get into what Junos term the Operational Mode (as per below). Once you click next at this point you will see image upload to your gns3 remote server.Ĭreate a new GNS3 project and drag your newly created Junos VM’s onto the project space.Ĭonnect the two devices to using add a link located on the left of the project space side. You will need a copy of the following ISO:Ĭlick the edit TAB and then select preferences. Upload your Junos image to your remote server. I have found when running devices locally they can be extremely laggy when having a number of devices running simultaneously.
You’ll be able to add many more devices and it will be a much more smoother experience simulating devices. To get the best performance out of GNS3 I recommend connecting to a remote GNS3 server. 3.This is a quick guide to get you started learning Junos OS using GNS3. The default password for the gns3 user is gns3.
You can do that using WinSCP on Windows Linux and OSX users can use the CLI and type in this command (replace GNS3_VM_IP_ADDRESS with the IP address of your GNS3 VM instance): scp OVMF-20160813.fd GNS3_VM_IP_ADDRESS:/home/gns3/ Unzip the downloaded OVMF-20160813.fd.zip, and copy OVMF-20160813.fd to the home directory of the gns3 user. Unzip the boot file and upload it to GNS3
Please note that you must have a service contract with Cisco in order to download it.
