🌐 Enterprise Network Design using Cisco Packet Tracer

A group project developed for the Computer Network course at Universiti Teknikal Malaysia Melaka (UTeM). This project demonstrates the design and implementation of a complete enterprise network using Cisco Packet Tracer, integrating routing, switching, network services, and security features.


📖 Project Overview

This project simulates a small enterprise network consisting of a Headquarters (HQ) and two Branch offices interconnected through routers. The network was designed to provide secure and efficient communication by implementing VLAN segmentation, Inter-VLAN Routing, dynamic routing, DHCP, DNS, Web Server, Mail Server, and Access Control Lists (ACLs).

The objective was to build a scalable and secure network infrastructure while applying industry-standard networking concepts using Cisco Packet Tracer.


🎯 Project Objectives

  • Design an enterprise network topology
  • Implement efficient IP addressing using VLSM
  • Configure VLAN segmentation
  • Enable Inter-VLAN Routing
  • Deploy dynamic routing using EIGRP
  • Configure DHCP services
  • Configure DNS services
  • Host a web server
  • Configure mail services
  • Secure the network using Access Control Lists (ACLs)

📖 What I Learned

Throughout this project, I gained hands-on experience in designing and configuring an enterprise network using Cisco Packet Tracer. I strengthened my understanding of routing and switching, network segmentation using VLANs, dynamic routing with EIGRP, network security using ACLs, and the deployment of essential network services such as DHCP, DNS, Web, and Email servers.
