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
Note: The --network lines correspond to: Vqfx-20.2r1.10-re-qemu.qcow2
: .qcow2 is a QEMU copy-on-write format, typically used in Linux KVM environments or network emulators like GNS3 , EVE-NG , or PNETLab . vqfx-20
# Create a directory for your lab mkdir ~/vqfx-lab cd ~/vqfx-lab Virtualization: Requires KVM/QEMU acceleration
The vQFX operates using a split architecture. To have a working switch, you must pair the RE image you have with a matching Packet Forwarding Engine (PFE) Routing Engine (RE): vqfx-20.2R1.10-re-qemu.qcow2 (Controls the device). Forwarding Engine (PFE): Typically named something like vqfx-20.2R1-2019010209-pfe-qemu.qcow (Handles the data traffic). 2. Common Integration Steps
