This stands for . In Juniper hardware, the RE handles control plane functions (routing tables, protocols, management). In the virtual world, this file specifically contains the Routing Engine image. (Note: A full vQFX deployment may also require a pfp image for the Packet Forwarding Engine, though later builds integrate them differently).
The file is the Routing Engine (RE) disk image for the Juniper vQFX10000 virtual switch, specifically version 20.2R1.10. Vqfx-20.2r1.10-re-qemu.qcow2
Using tools like vrnetlab to integrate Junos testing into automated network workflows. This stands for
