: The RE image handles protocols like OSPF, BGP, and STP, as well as SSH access and the Junos CLI.

: Stands for Routing Engine . In a vQFX setup, you typically need two separate virtual machines: one for the RE and one for the PFE (Packet Forwarding Engine) . vqfx202r110reqemuqcow2 exclusive

Network engineers primarily use this image to build complex topologies in virtual labs: Qemu image namings - - EVE-NG : The RE image handles protocols like OSPF,

: Indicates that the image is optimized for the QEMU (Quick Emulator) hypervisor. Network engineers primarily use this image to build

While physical switches integrate all components into one chassis, the virtual vQFX separates them to run more efficiently on standard server hardware.

: This is the Junos OS version. "20.2" is the release year and series, "R1" indicates the first revision, and ".10" is the specific build number.

: The file extension for QEMU Copy-On-Write version 2 . This is a versatile disk image format that supports thin provisioning, meaning the file only grows as data is actually written to it, saving significant disk space on the host machine. The Role of the RE Image
