Explanation:
Ref: Juniper Networks Partner Solution Development Platform: Architecture of the JUNOS System
“Architecture of the JUNOS System
…
The Routing Engine operates all routing protocols and makes all routing decisions by creating a routing table that includes the best path to each destination. The router writes these paths to a forwarding table in the Routing Engine and then copies the same data to the forwarding table on the Packet Forwarding Engine (PFE) which actually forwards the packets.
…
The Control Plane
…
The control plane runs on the Routing Engine. Its role is to manage and control the behavior of the device, including the data plane and the services plane.
