Unlike modern vMX versions (14.1R5 and later), which split the router into two distinct VMs—the virtual Control Plane (vCP) and the virtual Forwarding Plane (vFP)—version 14.1R4.8 can operate as a system. : Used as the base image for creating
Junos certifications (JNCIA, JNCIP, JNCIE) once featured labs based on 14.x code. Candidates studying older exam blueprints may still spin up vMX instances using this image. Candidates studying older exam blueprints may still spin
Do not deploy this image in any environment connected to production traffic. If you must analyze it, do so in a tightly controlled, offline lab. For any real routing task—virtual or physical—obtain a current, supported release from Juniper Networks under a proper license agreement.
However, the 14.1R4.8 version integrates both planes into a single image. This offers several advantages for lab environments: Resource Efficiency
