This overlay file will initially be 200KB but will grow as the switch writes logs and configs.
These are features that work specifically in the environment, not available on all physical switches:
The vqfx-20.2R1.10-re-qemu.qcow2 image is the core component of Juniper Networks' , which is the virtualized, software-based version of the QFX10000 modular Ethernet switches. Physical QFX10000 switches deliver up to 96 Tbps of system throughput and unparalleled 100GbE port density. Designed for large-scale data centers, they provide high-density 100G/40G/10G interfaces and serve as a fundamental building block for spine-and-leaf (Clos) fabric architectures. The vQFX aims to replicate this experience in a virtual environment. vqfx202r110reqemuqcow2 exclusive
