🌐 Enterprise Network Simulation – Cisco Packet Tracer

📦 Overview

This project simulates a complete simple enterprise computer network using Cisco Packet Tracer as part of the IT Platforms course (Winter 2024/2025).

It includes:

• 3 subnets with switches, routers, workstations, and mobile devices
• DNS, Web, and DHCP servers
• Class A addressing for WAN and Class C for LAN
• Wireless and wired access
• RIP-based dynamic routing
• Optical fiber links between routers

📁 .pkt simulation file and full technical report included

🧠 Project Goals

• ✅ Design and build a multi-subnet enterprise network
• ✅ Configure DHCP, DNS, and Web servers
• ✅ Enable WAN–LAN communication using Class A & C IP addresses
• ✅ Implement dynamic routing with RIP
• ✅ Test connectivity, DNS resolution, and web access

🖥️ Network Features

• 🖧 3 Subnets connected via 4 routers
• 🌐 WAN connection via Router-PT R6
• 🧱 Firewall (ASA0) for subnet isolation and security
• 🛰️ Access Points for mobile & wireless devices
• 📡 DHCP-enabled laptops, PCs, smartphones
• 🔒 WPA2 wireless encryption
• ⚡ Optical fiber used between routers for fast internal routing
