🎯 Project Overview

This project involved designing and implementing a complete enterprise network for Vic Modern Hotel using Cisco Packet Tracer. The hotel spans three floors with eight departments, each requiring isolated network segments, dynamic IP addressing, wireless access, and secure remote management.

The design follows a hierarchical network model with three routers (one per floor), inter-connected via serial DCE links, and uses OSPF for dynamic route advertisement across the entire site.

⚙️ Technologies Implemented

  • Hierarchical Network Design — three dedicated floor routers in the server room (IT dept, 3rd floor), all connected via serial DCE cable using inter-router networks 10.10.10.0/30, 10.10.10.4/30, and 10.10.10.8/30.
  • VLANs — eight department VLANs, one per department, trunked from routers to floor switches.
  • Inter-VLAN Routing (Router-on-a-Stick) — sub-interfaces on each router for inter-VLAN communication.
  • OSPF Routing — all routers configured to advertise and share routes dynamically.
  • DHCP — each router acts as the DHCP server for its attached VLANs; all devices receive dynamic IPs.
  • SSH — configured on all routers for secure remote login; tested and verified.
  • Wireless (WLAN) — Cisco Access Points deployed per floor; laptops and phones connect wirelessly.
  • Port Security — IT department switch configured with sticky MAC address learning on fa0/1; violation mode: shutdown.
  • Printers — one printer per department, connected and verified.
