e1000 or virtio-net-pci (Ensure the internal interconnect interfaces match precisely on both RE and PFE nodes). Step-by-Step EVE-NG Installation Guide
To get this specific image working, you typically need its counterpart, the PFE (Packet Forwarding Engine)
The is the specific QEMU-formatted disk image for the Routing Engine (RE) of Juniper’s vQFX 20.2R1.10 virtual switch. In a virtualized environment, this image acts as the "brain" of the switch, handling the control plane and management, while a separate Packet Forwarding Engine (PFE) image handles the data plane.
Support for Junos PyEZ, Ansible, and NETCONF, allowing engineers to validate automation scripts before deploying to live QFX5100/5200 series switches. vqfx202r110reqemuqcow2 work
He sighed. The lab’s physical switches were already racked and cabled for the new data center simulation, but the budget had been cut. Again. No hardware meant he had to build the entire spine-leaf topology in software.
He was in. The RE (Routing Engine) was alive.
The 20.2R1.10 release is a stable, feature-rich version of the vQFX RE. It excels in simulating complex Junos topologies within GNS3, EVE-NG, or PNETLab. While it is resource-intensive, it provides an authentic Junos experience that is nearly identical to physical hardware. Technical Performance Support for Junos PyEZ, Ansible, and NETCONF, allowing
Testing complex BGP confederations or EVPN-VXLAN fabrics without physical hardware.
This creates a new, empty QCOW2 image named my-disk.qcow2 with a maximum size of 10GB.
Although the filename says 20.2, some users report the image actually runs version 19.4R1 . Implementation Tips 💡
Since virtual disks can corrupt, always keep a backup of your set commands. Final Verdict
