vqfx-20.2r1.10-re-qemu.qcow2

A white paper or technical guide for the image would focus on its role as the Routing Engine (RE) component of Juniper's virtualized QFX10000 switch series. This image is designed for network emulation platforms like GNS3 and Containerlab to simulate complex Data Center (DC) fabrics. Technical Overview: Juniper vQFX 20.2R1.10

    Hypervisor

    | Attribute | Value | | :--- | :--- | | | QEMU / KVM (Linux KVM, Proxmox, OpenStack) | | Disk Format | QCOW2 (supports snapshots, compression, backfiles) | | Default CPU | 1-2 vCPU (vQFX RE is not CPU heavy) | | Default RAM | 4 GB (Minimum) to 8 GB (Recommended for 20.2) | | Disk Size | Typically ~2 GB compressed, ~8-12 GB uncompressed | | Architecture | x86_64 (AMD64) | | OS Inside | Junos OS (FreeBSD kernel-based) | | Data Plane | Not in this file (Requires separate vqfx-pfe image) | vqfx-20

    Forwarding performance

    | Area | Limitation | |------|-------------| | | PFE is software-emulated – <1 Gbps, high latency. | | EVPN | Partial support – use 21.x or later for production-like EVPN. | | VXLAN routing | May require rebooting PFE after changes. | | SNMP bulk walks | Can cause RE CPU spikes. | | Graceful Routing Engine Switchover (GRES) | Not supported in single-RE images. | | Upgrade path | Must upgrade both RE and PFE images together; 20.2 → 21.2 is possible but nontrivial. | QEMU disk image filename This looks like a
