The file vqfx-20.2R1.10-re-qemu.qcow2 is the virtual disk image for the Routing Engine (RE) of Juniper’s vQFX10000 virtual switch. It is designed for use in network simulation environments like GNS3, EVE-NG, and Containerlab. 🛠 Device Architecture
Key Connection TipFor the switch to "boot" properly, you must connect the specific internal interfaces between the RE and PFE. Typically, em1 on the RE connects directly to em1 on the PFE.
