Vqfx202r110reqemuqcow2: [portable]

Because the image runs authentic Junos OS, it provides a perfect sandbox for developing Python scripts, Ansible playbooks, and NETCONF integrations.

If you need a setup for control plane access or a VXLAN EVPN configuration example using this image, just ask.

: This is the crown jewel. The QCOW2 (QEMU Copy On Write version 2) format is the industry standard for QEMU-based virtualization. It is the file format of this image. Its key features make it indispensable for lab use: vqfx202r110reqemuqcow2
