TechNova enterprise network in Packet Tracer

What this is

While studying for my NDICT (NVQ Level 5), I turned my networking practicals into a practical book in Cisco Packet Tracer: 15+ labs and projects, from a first LAN to a full enterprise network design.

Every lab comes with the .pkt file, so you can open a working network, read the configuration, break it and fix it. Each lab also has its own step-by-step guide with verification commands.

Highlights

Capstone and the 80-workstation design

The TechNova enterprise network is a hierarchical design for a fictional mid-sized company: VLANs per department, routing, port security, ACLs, SSH, network services and wireless. My NVQ final proposal, a network lab for 80 workstations for an IT institute with three computer labs, is in its own repository with a cost estimate.

How to use the labs

  1. Get Cisco Packet Tracer free from Cisco Networking Academy (the labs use 8.1 or newer).
  2. Clone the repository or download it as a ZIP.
  3. Open a lab folder, double-click the .pkt file and follow that folder's guide.

Tip: use Simulation mode to watch packets move hop by hop, and break a lab on purpose, then use the show commands from the guide to find the fault.
