Device: AKWAA-EDGE (ASN 65001)

Role: BGP peering with ISP, default route for lab

Edge Router Configs

Troubleshooting Workflow

1. Identify the symptom (e.g., BGP down, no internet, ping fails)
2. Check physical and interface status (Layer 1)
3. Verify Layer 2 and Layer 3 configs (encapsulation, IPs, routing)
4. Check BGP session and routes
5. Use pings/traceroutes to isolate the problem
6. Check logs and debug if needed
7. Fix and verify (clear BGP session, correct configs, etc.)

Troubleshooting Checklist

1. Physical & Interface Layer (Layer 1)

• [ ] Check cable and link status

  • Are interfaces physically connected and showing link lights?

  

2. Data Link Layer (Layer 2)

• [ ] Verify encapsulation and errors
  • Make sure correct encapsulation is used (Ethernet for most lab links).
  • Check for errors or excessive drops.

3. Network Layer (Layer 3)
