NIT1104 Computer Networks: Ethernet LAN Design Project Solution

This document presents a comprehensive solution to an Ethernet LAN design project. It includes a detailed network diagram illustrating the local area network topology, a site map showing the deployment location, and a complete network inventory list specifying the hardware and cables required, along with their costs. The project also features an IP addressing plan, outlining the major network and subnet allocations, ensuring efficient address space utilization. Furthermore, the document provides detailed configuration commands for all routers and switches, accompanied by screenshots from the Packet Tracer file, demonstrating the practical implementation of the network design. The design adheres to the specifications provided in the assignment brief, ensuring each PC lab is on a separate IP sub-network, all office computers are on a single IP sub-network, and the LAN is connected to the main campus network via a FastEthernet fiber optic link.
