Network Infrastructure & Design

LAN, VLAN & Server Configuration

This project demonstrates a comprehensive approach to network architecture at an undergraduate level. It focuses on the implementation of Local Area Networks (LAN) and Virtual LANs (VLANs) to logically segment broadcast domains, enhancing both security and network efficiency. The configuration includes robust Web Server setups and inter-VLAN routing protocols, all simulated and validated using Cisco Packet Tracer to ensure industry-standard connectivity and performance.


Full Network Topology

Full Project Topology

A comprehensive overview of the entire simulated network, showcasing the integration of routers, L3 switches, and departmental end devices across multiple Virtual LAN segments.

VLAN Configuration

VLAN Logical Setup

Logic-based segmentation of the network into distinct VLANs (Accounting, IT, HR), effectively reducing broadcast traffic and enhancing internal security through isolated broadcast domains.

Router & Switch Config

Switching & Routing

Implementation of Inter-VLAN routing using Router-on-a-Stick and Layer 3 switching techniques, enabling controlled communication between different subnetworks.

Web Server Setup

Web Server Integration

Configuring centralized HTTP/HTTPS services within a dedicated server farm VLAN, ensuring high availability and secure access for all client terminals in the infrastructure.

IP Addressing Table

Addressing Schema

A systematic IP assignment using Variable Length Subnet Masking (VLSM) to optimize address space utilization and ensure scalable growth within the hierarchical network design.

Connectivity Testing

Ping & Trace Testing

Rigorous validation phase using end-to-end ICMP testing (Ping) to verify zero-packet-loss connectivity and trace-route analysis to confirm optimal path selection.
