## Overview

Castle Rysen is an educational Cisco Packet Tracer network design. Its principal workflow is segmented cafe and shelter networks providing user connectivity, with the shelter also providing upstream connectivity toward the cafe and Internet. The README documents switching, routing, services, and security capabilities, but source excerpts and device-level topology details are unavailable; links therefore show only documented relationships.
