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.
Below are the official Cisco Networking Academy courses I have completed. Click on each course title to expand the section and view the corresponding certificates and verifiable badge.

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 repository is structured as a series of labs, each building on the last.
| Lab # | Lab Title & Link | Key Concepts Covered |
|---|---|---|
| 01 | Router Basic Configuration | Hostname, Privileged EXEC Password, Saving Configurations. |
| 02-03 | Router Interface & DHCP | IP Address Assignment, Enabling Interfaces, DHCP Server Setup. |
| 04 | Static Routing | Connecting separate LANs using manually configured static routes. |
| 05-06 | Dynamic Routing (RIP & EIGRP) | RIPv2, EIGRP, Administrative Distance, Automatic Network Discovery. |
| 07 | OSPF Routing | Single-Area OSPF, Link-State Routing, OSPF Neighbor Adjacencies. |
| 08 | Switching - Spanning Tree Protocol (STP) | Loop Prevention, Root Bridge Election, PortFast, BPDU Guard. |
| 09 | Switching - VLANs & Inter-VLAN Routing | VLAN Creation, VTP, 802.1Q Trunking, SVIs, "Router-on-a-Stick". |
| 10 | Switching - LACP EtherChannel | Link Aggregation, Redundancy, Increased Bandwidth with LACP. |
| 11 | Management Services (NTP, Logging, SNMP) | Time Sync, Centralized Logging, Network Monitoring. |
| 12 | Security with Access Control Lists (ACLs) | Standard & Extended ACLs, Traffic Filtering, VTY line security. |
| 13 | Final Enterprise Network Lab | (Capstone) Integration of all previous concepts into a multi-site 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.
All labs were designed and tested using Cisco Packet Tracer (v8.x or later).
- Navigate to a Lab Folder: Each numbered folder represents a self-contained lab.
- Read the Instructions: The
README.mdfile inside each folder provides a detailed objective, topology diagram, configuration steps, and verification commands. - Run the Lab: Open the
.pktfile in Cisco Packet Tracer to interact with the pre-built topology. - Reference the Commands: The
configs/commands.txtfile in each lab folder contains a complete, ready-to-use script of all the configurations applied to the devices.
