## Overview

This repository is a Cisco Packet Tracer design for an interconnected school network serving the Pelayo and Córcega campuses. Its documented workflow carries campus users’ traffic through department VLANs and inter-VLAN gateways, across redundant inter-site links, and toward protected school services or simulated Internet access. The design also includes structured cabling, wireless access, and a DMZ. The Packet Tracer file is the only implementation artifact; relationships below rely on the README, since no source excerpts were available to verify device-level configuration.

Main entry points: [`XARXA ESCOLA.pkt`](https://github.com/polmates-collab/xarxa_escola/blob/main/XARXA%20ESCOLA.pkt) (Department VLANs)
