🚀 CCNA 200-301 Lab Journey: From Basics to a Full Enterprise Network
Welcome to my comprehensive repository of Cisco Packet Tracer labs, documenting my hands-on journey through the Cisco Certified Network Associate (CCNA) curriculum. This collection starts with fundamental concepts and progressively builds upon them, culminating in a final capstone project that integrates all learned skills into a realistic, multi-site enterprise network.
This repository serves as both a personal learning journal and a practical resource for anyone studying for the CCNA certification. Each lab is self-contained, with detailed instructions, configuration files, and verification steps.

🛠️ Technologies and Skills Covered
This series of labs provides hands-on experience with a wide range of networking technologies, including:
- Routing: Basic Router Configuration, Static Routing, and Dynamic Routing Protocols (RIP, EIGRP, OSPF).
- Switching: VLANs, 802.1Q Trunking, Spanning Tree Protocol (STP), PortFast, BPDU Guard, and EtherChannel (LACP).
- IP Services: DHCP Server Configuration, Network Time Protocol (NTP), and Syslog.
- Network Security: Standard and Extended Access Control Lists (ACLs) for traffic filtering and securing VTY access.
- Network Management: Simple Network Management Protocol (SNMP) for device monitoring.
- WAN Technologies: Serial link configuration and multi-site connectivity.

🏆 The Capstone Project: Lab 13 - Final Enterprise Network
The final lab is a culmination of all the skills acquired. It involves building a complete enterprise network featuring a central headquarters, two remote branch offices, and a service provider backbone. This project integrates routing, switching, security, and management services into a single, cohesive, and functional network.
💻 Software Requirements
All labs were designed and tested using Cisco Packet Tracer (v8.x or later).
📖 How to Use This Repository
