🛠️ Technologies Used

• Cisco Packet Tracer
• Routing Protocol: EIGRP (AS 10)
• VLANs for network segmentation
• Router-on-a-Stick architecture
• DHCP for dynamic IP allocation
• ACLs for access control
• Cisco IOS CLI for configuration Voip & Python Intergration

---

🌐 Network Features

• Inter-city routing using EIGRP
• VLAN-based departmental segmentation
• Dynamic IP assignment via DHCP
• Access Control Lists to restrict unauthorized traffic
• Secure router configuration using:
  • enable secret
  • service password-encryption
  • no ip domain-lookup
