I needed a Juniper virtual lab to refresh my Junos OS CLI, so the easiest way is to deploy a virtual MX (vMX) in GNS3. You'll need a vMX qcow2 file to run in GNS3.
Go to Edit >Preferences > QEMU > Qemu VM >New > select New Image >browse the .qcow2 file.
It will automatically upload the image. Just click Finish when it's done.
Select vMX > click Edit.
Under Symbol > click Browse.
To distinguish between a Cisco and Juniper router, under General settings tab > Symbol > select: Affinity-circle-blue > select: Router > click OK.
Go to Network tab > Adapters: type 3 (or click up arrow).
Click OK > Apply.
Click Browse all devices (left-hand side) > click/drag vMX.
I've deployed two vMX, a Cisco L2 switch and a Cisco 7200 router in my JNCIA lab.
I just ran/power on a single vMX and the L2 switch to play around with Junos CLI.
