IT 127 Final Project: Designing and Implementing a Secure Inter-VLAN Network
with OSPF, VLANs, ACLs, DHCP, and Wireless
Project Overview
Students will design, configure, and simulate a small enterprise network using Cisco
Packet Tracer. The network must include:







Multiple VLANs for different departments
Inter-VLAN routing using a Layer 3 device
Dynamic routing with OSPF
Access Control Lists to enforce security policies
DHCP for automatic IP addressing
Wireless access for mobile users in one department
Documentation and presentation to showcase the design and configuration
Project Objectives






Segment the network using VLANs
Configure inter-VLAN routing and OSPF
Implement ACLs to secure traffic
Set up DHCP server(s) to automate IP address allocation
Deploy and secure a wireless LAN
Document and present the entire configuration and design
Scenario
A fictional company, your group name, has four departments:
1. HR Department
2. IT Department
3. Finance Department
4. Marketing Department (Mobile/Wireless)
Each department must be on a separate VLAN. The network is spread across 2
routers and 4 switches. All VLANs must communicate through Inter-VLAN Routing
using a Layer 3 switch. The two routers must be connected using OSPF. DHCP must
be configured to automatically assign IP addresses per VLAN. Wireless access must
be available for the Marketing department, with WPA2 security. ACLs must restrict
the following:



HR department cannot access Finance servers.
Only IT can SSH/telnet into routers and switches.
Wireless clients can access the Internet and public servers only.
