I can provide the exact configuration snippets or node template settings for your environment.

This is the "brain" of the switch. It runs the Junos control plane, handling protocols like BGP, OSPF, and EVPN-VXLAN. The Forwarding Engine (PFE/VFP): vqfx202r110reqemuqcow2

The RE serves as the brains of the switch. It runs the Junos control plane, managing routing protocols (OSPF, BGP), user access (SSH, Netconf), and configuration databases. The vqfx202r110reqemuqcow2 file represents this specific Routing Engine component for version 20.2R1.10. 2. The Packet Forwarding Engine (PFE) VM

If you encounter issues with this specific image, consider the following troubleshooting steps:

The Juniper vQFX10000 is a virtualized version of the high-performance QFX10000 data center switch. For network engineers, architects, and students looking to build realistic network labs without expensive hardware, the vQFX is an essential tool. The vqfx202r110reqemuqcow2 image is large and needs time

| | Cons | | :--- | :--- | | High Fidelity: Excellent for learning EVPN-VXLAN and Data Center fabrics. | Resource Heavy: Consumes significant RAM/CPU per node. | | Modern Code: Version 20.2 supports newer Junos features and ELS syntax. | Slow Boot: Takes 3-6 minutes to fully boot and pass traffic. | | ELS Support: Matches the syntax used on modern physical QFX devices. | Fragile: Prone to corruption if not shut down gracefully. | | Free Labbing: Allows testing expensive hardware architectures for free. | Data Plane Lag: The virtual PFE can sometimes lag behind the control plane. |

: Operates similarly to Eve-NG, leveraging the KVM hypervisor beneath the hood to spawn the node. System Requirements per Instance
