Design and Implementation of a Small Enterprise Network

[OVERVIEW]

This project focuses on designing and implementing a secure and scalable enterprise network for the College of Information and Communications Technology (CICT). The simulated network supports three departments—Administration, Faculty, and Students—each isolated using VLANs while maintaining inter-department communication through routing. The project demonstrates practical applications of network design principles, routing protocols, and basic network security.

[KEY FEATURES]

• Departmental separation using VLANs for Administration, Faculty, and Students
• Inter-VLAN communication using Router-on-a-Stick configuration
• Dynamic routing implementation using OSPF across three routers
• Automatic IP address allocation via centralized DHCP configuration
• Deployment of DNS and Web services on a dedicated server network
• Basic network security through port security, device passwords, and controlled access

[TECHNICAL DETAILS]

The network was implemented using Cisco-based configurations with a focus on real-world enterprise practices. Layer 2 switches handle VLAN segmentation and trunking, while routers manage inter-VLAN routing and dynamic routing using OSPF. Subnetting was applied to efficiently allocate IP address ranges per department. Additional configurations include DHCP services, server setup for DNS and HTTP/HTTPS, port security on switches, and basic router and switch hardening.
