This stands for . The QFX series is Juniper’s line of high-performance data center switches. The virtual version allows you to emulate a QFX5100 or QFX10000-style switch using KVM (Kernel-based Virtual Machine). vqfx202r110reqemuqcow2 exclusive

This reduces host CPU from 100% to ~15% per instance.

The file format qcow2 is specific to QEMU-based emulation.

These are features that work specifically in the environment, not available on all physical switches: In the realm of technology, coding, and digital

At first glance, the string vqfx202r110reqemuqcow2 appears dense, but it tells a precise technical story. It is a concatenated representation of the file vqfx-20.2R1.10-re-qemu.qcow2 , a primary disk image used to emulate the Routing Engine (RE) of a Juniper Networks vQFX10000 virtual switch.

Minimum 2048 MB (2 GB). Allocating 3072 MB (3 GB) improves boot times and stability during complex BGP/EVPN testing.

Your vQFX is now ready to route, switch, and run EVPN. The QFX series is Juniper’s line of high-performance
