# Create a directory for your lab mkdir ~/vqfx-lab cd ~/vqfx-lab
In the world of network engineering, the gap between theory and practice has traditionally been bridged by expensive hardware. For decades, mastering a platform like Juniper’s Junos OS meant investing in physical routing and switching platforms. However, the virtualization revolution has democratized network engineering. At the heart of this revolution for Juniper enthusiasts lies a specific, powerful file: . Vqfx-20.2r1.10-re-qemu.qcow2
The Vqfx-20.2r1.10-re-qemu.qcow2 file can be used in a variety of scenarios: # Create a directory for your lab mkdir
: For the Routing Engine (RE) VM, assign at least 1024 MB RAM and 2 vCPUs . At the heart of this revolution for Juniper
A separate image (often named vqfx-20.2R1-pfe-qemu.qcow2 ) that acts as the data plane, performing the actual packet switching and forwarding. Deployment & Requirements
