vqfx-20.2R1.10-re-qemu.qcow2 Routing Engine (RE) disk image for the Juniper vQFX virtual switch. To use it effectively in a network lab (like GNS3, EVE-NG, or CML), it must be paired with a corresponding Packet Forwarding Engine (PFE) Technical Overview & Setup Guide 1. System Requirements Minimum 1024 MB RAM for the RE. Virtualization: Requires KVM/QEMU acceleration. Default Credentials: (Note: Capital 'J'). 2. Architecture & Connectivity

1. JunOS Certification & Training (JNCIP/JNCIE) – Practice routing protocols (BGP, OSPF, ISIS) and switching features.
2. Network Automation Testing – Test Ansible, Salt, or PyEZ scripts against a virtual Juniper switch.
3. Multivendor Topology Simulation – Integrate with vMX, vSRX, Cisco IOSv, or Arista vEOS in EVE-NG/GNS3.
4. EVPN/VXLAN Testing – vQFX is commonly used for data center fabric simulations (though note limitations in 20.2).

# ... other operations ...

Note: For a functional switch, you must also link this instance to a corresponding PFE instance. Benefits of the 20.2R1.10 Release

For stable operation in a virtual environment, follow these recommended resource allocations: Guide: Importing Juniper vMX and vQFX into CML2.4

Considerations

• Linux host with libvirt/virt-manager or qemu-kvm.
• The PFE image (vqfx-20.2r1.10-pfe-qemu.qcow2).
• A bridging interface (e.g., br0).
