🟢 SWITCHES (4 TOTAL)

4️⃣ DIST-SW1 — Cisco 2960

What it does:

  • VLAN 20 (Servers)
  • VLAN 30 (Wi-Fi)
  • Access ports only

7️⃣ BR-SW4 — Cisco 2960

Role: Branch Access Switch

What it does:

  • Branch user connectivity
  • Simple access-layer design

🟣 END DEVICES

8️⃣ PC-PT (Multiple)

Role: End-user devices

Used for:

  • VLAN testing
  • DHCP testing
  • ACL testing
  • Troubleshooting

9️⃣ Server-PT

Role: Server (Future Labs)

Used for:

  • DHCP (later)
  • DNS
  • HTTP / HTTPS
  • FTP
  • CCNA server-based services

🔟 Laptop-PT

Role: Wireless client

Used for:

  • Wi-Fi testing
  • Wireless security basics

📡 WIRELESS

1️⃣1️⃣ WRT300N

Role: Wireless Router / AP (CCNA level)

Used for:

  • Basic wireless concepts
  • SSID
  • WPA2
  • VLAN integration (basic)

⚠️ CCNA does NOT use WLCs — this is correct.


☁️ WAN / ISP SIMULATION

1️⃣2️⃣ Cloud-PT

Role: ISP Core / Internet Simulation

Used for:

  • WAN abstraction
  • NAT testing
  • Internet reachability

Optional but recommended.


🧠 ARCHITECTURE STATUS (IMPORTANT)

CURRENT STATE

  • Physical design: Collapsed core
  • Logical roles: Access / Distribution / Core present
  • Inter-VLAN routing: Router-on-a-Stick

FUTURE STATE

  • True three-tier
  • Layer-3 Distribution switch
  • Router = WAN only
  • Enterprise-style campus

🧩 CCNA TOPICS THIS LAB WILL COVER (100%)

✔ IP addressing
✔ VLANs & Trunks
✔ ROAS
✔ DHCP & DHCP relay
✔ OSPF (single + multi-area)
✔ Standard & Extended ACLs
✔ NAT
✔ WAN concepts
✔ Wireless basics
✔ IPv6
✔ Troubleshooting


✅ One sentence to lock this in

This single lab uses 3 routers, 4 switches, and standard CCNA devices to cover every CCNA concept now and evolve cleanly into CCNP-style design later.


📘 What We Are Creating (Simple Overview)

We are building one complete enterprise network lab that starts simple and gradually grows to cover every CCNA 200-301 topic, using realistic devices and roles.

Instead of many small labs, this is one evolving network that students understand deeply and improve step by step.


🏢 The Network We Are Building

We are simulating a company with two locations:

  • Head Office (HQ)
  • Branch Office

Both locations are connected using a WAN (wide area network), just like real companies.


🔧 Devices and How They Are Linked

1️⃣ End Devices (PCs, Laptop, Server)

  • PCs represent users
  • Laptop represents Wi-Fi users
  • Server represents company services (DNS, DHCP, web later)

These devices connect to access switches.


2️⃣ Access Switches (HQ-SW2, HQ-SW3, BR-SW4)

  • Access switches connect end devices
  • Each device is placed into a VLAN (Users, Servers, Wi-Fi)
  • This separates traffic for security and performance

Why:

End devices should not all be in one big network.


3️⃣ Distribution Switch (DIST-SW1)

  • Connects all access switches together
  • Uses trunk links to carry multiple VLANs
  • Acts as the central point inside HQ

Why:

It keeps the network organised and scalable instead of messy switch-to-switch connections.


4️⃣ Head Office Router (HO-R1)

  • Connects the HQ network to the WAN
  • Routes traffic between VLANs (initially using Router-on-a-Stick)
  • Runs OSPF for routing
  • Provides DHCP (automatic IP addresses)
  • Later handles NAT for Internet access

Why:

Routers connect different networks and different locations.


5️⃣ Branch Router (BR-R2)

  • Connects the branch network to HQ
  • Acts as the gateway for branch users
  • Runs OSPF
  • Later uses DHCP relay

Why:

Each site needs its own router to access the wider network.


6️⃣ ISP Router (R0) and Cloud

  • R0 represents the ISP edge router
  • Cloud represents the rest of the Internet / ISP core
  • Used to practice Internet access and NAT

Why:

Companies do not control the Internet — they only connect to it.


🌐 How Traffic Flows (Big Picture)

User PC
 ↓
Access Switch (VLAN)
 ↓
Distribution Switch (Trunk)
 ↓
HQ Router (Routing / WAN)
 ↓
Branch Router or ISP

Traffic always moves:

  • Layer 2 (switching) inside VLANs
  • Layer 3 (routing) between VLANs and locations

🏗️ Why This Design Is Used

This setup allows us to:

  • Separate users, servers, and Wi-Fi using VLANs
  • Control traffic using ACLs
  • Automatically assign IPs using DHCP
  • Connect locations using OSPF
  • Access the Internet using NAT
  • Start with a collapsed core (simple)
  • Later upgrade to a true three-tier design

Why this matters:

This is how real enterprise networks are built and upgraded over time.


🎯 Learning Benefit (Why This Is Powerful)

With this one lab, students will learn:

  • How small networks grow into enterprise networks
  • Why each device exists
  • How traffic moves and is controlled
  • How CCNA concepts fit together logically

No memorising.
No random labs.
Just real understanding.
