In this step, we will review and consolidate everything we have done so far, from network architecture to device connections. This step ensures you understand the full setup and are ready to proceed with further configurations and labs.
1. Network Architecture Overview (Step 1 Recap)
- The network consists of routers, distribution switches, and access switches.
- Core concepts:
- Routers connect different networks.
- Switches connect multiple devices within the same network.
- Hierarchical model: Core → Distribution → Access.
2. Packet Tracer Setup and Device Download (Step 2 Recap)
- Ensure you have Packet Tracer installed.
- Download and add all required devices:
- Routers (R1, R2, R3)
- Switches (SW1, SW2, SW3)
- End devices (PCs, laptops as needed)
3. Adding Serial Ports to Routers (Step 3 Recap)
- Routers R2 and R3 require serial ports for WAN connections.
- Steps:
- Go to Physical View → Modules
- Insert WIC-2T serial modules
- Ensure module is powered on
4. Connecting R1 to Distribution Switch SW1 (Step 4 Recap)
- Connect R1 to SW1 using copper straight-through cable (Ethernet).
- Verify:
- Ports on SW1 match R1 interfaces.
- Device LEDs indicate link is active.
5. Connecting SW1 to Access Switch SW2 (Step 5 Recap)
- Connect SW1 (distribution) to SW2 (access) using copper straight-through cable.
- This ensures devices connected to SW2 can reach the network through SW1.
6. Connecting SW1 to Access Switch SW3 (Step 6 Recap)
- Connect SW1 (distribution) to SW3 (access) using copper straight-through cable.
- This allows devices on SW3 to communicate with the network via SW1.
7. Final Topology Check
- Verify all connections:
- Routers to distribution switch
- Distribution switch to access switches
- Serial ports on R2 and R3 installed correctly
- Make sure all device LEDs are green (active link).
- This ensures your network architecture is fully functional before moving to configuration labs.
✅ Tip: After this revision, your network should match the topology from Step 1, with all routers, switches, and connections in place. You are now ready for IP addressing, routing, and lab exercises.
