Hotel System
Network Design
A full enterprise network design and implementation for Vic Modern Hotel — a three-floor building with eight departments — using Cisco Packet Tracer with VLANs, OSPF routing, DHCP, SSH, wireless networking, and port security.
🎯 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.
🏗️ VLAN & IP Scheme
| Floor | Department | VLAN | Network |
|---|---|---|---|
| 1st Floor | Reception | VLAN 80 | 192.168.8.0/24 |
| 1st Floor | Store | VLAN 70 | 192.168.7.0/24 |
| 1st Floor | Logistics | VLAN 60 | 192.168.6.0/24 |
| 2nd Floor | Finance | VLAN 50 | 192.168.5.0/24 |
| 2nd Floor | HR | VLAN 40 | 192.168.4.0/24 |
| 2nd Floor | Sales / Marketing | VLAN 30 | 192.168.3.0/24 |
| 3rd Floor | Admin | VLAN 20 | 192.168.2.0/24 |
| 3rd Floor | IT | VLAN 10 | 192.168.1.0/24 |
⚙️ 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, and10.10.10.8/30. - 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.
