Vqfx-20.2r1.10-re-qemu.qcow2 [upd]

As reported by containerlab , sometimes early versions of the vQFX 20.2 package were actually 19.4 internally. It is crucial to check the output of show version within the CLI to ensure you are running the expected JUNOS version, notes this Juniper community discussion . How to Use vqfx-20.2r1.10-re-qemu.qcow2 in Virtual Labs

Power on the PFE node first, wait roughly 60 seconds, and then power on the RE node. This sequence ensures that when the Junos kernel boots up on the RE, the simulated ASIC listener is already alive and ready to register interfaces. Once successfully paired, log into the RE CLI and execute: show interfaces terse Use code with caution.

Default username is root with password Juniper (case-sensitive) or sometimes admin with admin@123 depending on the lab distribution. Lab Specifications

The vQFX image Vqfx-20.2R1.10-re-qemu.qcow2 is more than just a file; it is a portable Junos environment that empowers network engineers to create robust, dynamic, and realistic virtual data center labs. It serves as a critical bridge between learning the Junos CLI and validating large-scale network changes without physical hardware. By understanding its ecosystem, mastering its deployment, and being prepared to troubleshoot its common quirks, you can harness the power of virtualization to accelerate your networking expertise.

Cisco Modeling Labs (formerly VIRL) also supports Juniper devices. You can import vQFX definitions by creating node and image definitions. This involves preparing a YAML definition file for the node and then using the CML WebUI to import the definition, after which the corresponding QEMU image can be associated.

After creating both RE and PFE nodes, ensure they are connected via their em1 interfaces.

EVE-NG relies on precise directory structures and naming conventions to recognize Qemu images. Follow these steps to import the vQFX RE image. Step 3.1: Create the Directory Structure

Double-check that em1 on the RE maps precisely to em1 on the PFE. Verify that the PFE node is powered on and running. 2. Continuous Boot Loops or Kernel Panics

: Includes improvements in EVPN-VXLAN, automation capabilities, and updated protocol support. This sequence ensures that when the Junos kernel

The .qcow2 format is natively supported by QEMU/KVM , making it compatible with GNS3 , EVE-NG, and standard Linux virtualization tools. Initial Credentials: Username: root Password: Juniper (Note: The password is case-sensitive). Known Issues & Versions

In EVE-NG, adding a vQFX is more structured, but it requires strict adherence to the . The .qcow2 files must be renamed to hda.qcow2 and placed in a folder named vqfxre-20.2R1.10 . The PFE image, if used, would follow its own format. It is important to note that vQFX in EVE-NG may have issues when EVE-NG itself is hosted on VMware. Users have reported success with an allocation of 2 vCPUs and 4GB of RAM for the RE VM to achieve stable performance.
