This CCNA Mega Lab was originally created by Jeremy’s IT Lab.
You can find his incredible free full CCNA video course on YouTube here:
I highly recommend Jeremy’s content — his educational material was instrumental in helping me pass the CCNA myself.
If you’re studying for the CCNA, his explanations and lab exercises are some of the best available for free.
The CCNA_MEGA_LAB by Jeremy’s IT Lab is a massive, hands-on configuration lab that can takes several hours to complete.
"This lab covers a complete network configuration from zero, including topics like IPv4 and IPv6, static routes, VLANs, spanning tree, OSPF, EtherChannel, DHCP, DNS, NAT, SSH, security features, wireless, and more – everything on the CCNA exam!"

This repository contains my version of the lab, including notes, configurations, and scoring screenshots from my run-through. If you would like to complete the lab yourself, please visit the links provided in the Homage section.
This lab includes a built-in percentage-based scoring mechanism that updates your completion score every time you save the configuration (using copy running-config startup-config or write memory).
I personally finished the lab at 98%, which is due to a few minor configuration preferences:
- In the HSRP section, Jeremy uses standby groups 1, 2, 3, etc.
I used the actual VLAN numbers for my standby groups instead. - Jeremy configured a priority of 105, while I used 110.
While these differences slightly lowered my score, they do not affect the lab’s functionality. I chose to leave them as-is to demonstrate alternative valid approaches rather than follow the lab word-for-word.
🖼️ Lab Scoring:
The LAN network consists of:
- 🖧 Six Access Switches
- 🏢 Four Distribution Switches
- 🧩 Two Core Switches
- 🌍 One Edge Router
The WLAN includes:
- 📡 One Wireless LAN Controller (WLC)
- 📶 Two managed Lightweight Access Points (LWAPs)

The repository is organized to make it easy to follow the lab, view configurations, diagrams, and testing results.

- This lab is designed for Cisco Packet Tracer environment.
- You’ll gain hands-on practice in nearly every CCNA exam domain.
- It’s a great final review lab before taking the Cisco CCNA (200-301) exam.
