Cisco Packet Tracer project for designing and validating a segmented LAN for a smart office environment.
The project demonstrates VLAN-based department separation, inter-VLAN routing, DHCP, NAT, switching features and basic access-control configuration.
The office network is split into departments and services:
| VLAN | Name | Subnet | Gateway |
|---|---|---|---|
| 10 | ADMIN | 192.168.10.0/24 |
192.168.10.1 |
| 20 | FIN_HR | 192.168.20.0/24 |
192.168.20.1 |
| 30 | SALES | 192.168.30.0/24 |
192.168.30.1 |
| 40 | IT | 192.168.40.0/24 |
192.168.40.1 |
| 50 | VOIP | 192.168.50.0/24 |
192.168.50.1 |
| 99 | GUEST_WIFI | 192.168.99.0/24 |
192.168.99.1 |
- Star-style LAN topology with a central Cisco router and Cisco 2960 switches
- VLAN segmentation by department
- Trunk links between switching/routing devices
- Inter-VLAN routing
- DHCP address allocation
- NAT for simulated external access
- STP verification
- VTP status verification
- Hierarchical local user access for router administration
Telnet is used only as a Packet Tracer lab mechanism. In production, SSH should be used instead.

This lab shows the ability to design, document and validate a small enterprise LAN with practical Cisco networking concepts. It is useful as a foundation for later automation work with GNS3, Netmiko and configuration backup/verification scripts.
- Add exported router and switch configuration files under
configs/ - Add a topology image under
docs/topology.png - Add validation command outputs under
validation/ - Add an ACL section to separate guest traffic more clearly
- Create a follow-up automation repo using GNS3 and Netmiko
