Project Overview

The Multi-Router LAN with Wireless Integration and Port Security Simulation is a Cisco Packet Tracer project that models a secure enterprise network.
It demonstrates LAN segmentation, multi-router configuration, wired and wireless connectivity, and network access control. Unauthorized or rogue devices are blocked using port security and MAC filtering, while legitimate users maintain seamless access.

The simulation emphasizes OSI and TCP/IP model alignment, RIP routing, and practical network security strategies applied to multi-department networks.
