This handles the data plane. Without it, your interfaces will show as "up" but won't actually switch traffic. The "Trick": Connect the interface of the RE directly to the
: To improve performance, you can convert the .qcow2 image to raw format using the qemu-img convert command:
Initial username is root , password is Juniper (capital J) [GNS3 Initiative]. vqfx202r110reqemuqcow2 work
Getting this image to "work" involves careful configuration of virtual resources and specific connectivity between the RE and PFE nodes. 1. Prerequisites and Resource Requirements
Because vqfx202r110reqemuqcow2 includes full EVPN support (unlike older vMX), it works flawlessly once PFE is online. This handles the data plane
As a QCOW2 (QEMU Copy-On-Write) file, it is natively designed for QEMU . It requires specific hardware acceleration (KVM) and CPU flags (typically host or IvyBridge ) to boot the Junos kernel efficiently.
Run containerized network labs with Docker, including Juniper vQFX nodes: Getting this image to "work" involves careful configuration
Encountering problems with vQFX is not uncommon, but here are several key fixes.
The RE image will boot and allow CLI access, but interfaces will remain "down" unless it is correctly linked to a running PFE instance via an internal bridge (typically using UDP tunnels or dedicated virtual links).
