From Zero to Network Engineer: A Comprehensive Hands-On Roadmap
Welcome to the ultimate CCNA practical training suite. This repository contains 10 meticulously designed Cisco Packet Tracer labs covering the core pillars of the CCNA 200-301 exam. Don't just read the OCG—build the network.
This bundle provides step-by-step configuration and troubleshooting scenarios for:
- VLANs & Trunking: Logical segmentation and 802.1Q tagging.
- Inter-VLAN Routing: Router-on-a-Stick and Layer 3 Switch configurations.
- STP (Spanning Tree Protocol): Preventing loops and understanding Root Bridge election.
- EtherChannel: Increasing bandwidth via Link Aggregation.
- OSPFv2: Single-area dynamic routing, neighbor adjacencies, and cost tuning.
- HSRP (First Hop Redundancy): Gateway redundancy for high availability.
- ACLs (Standard & Extended): Traffic filtering and security.
- NAT (Static & PAT): Mapping private IP space to the public internet.
- DHCP & Port Security: Automated addressing and Layer 2 hardware lockdown.
- The Enterprise Lab: A capstone project integrating all the above into one cohesive topology.
We don't just give you files; we give you a path. Included in this repo is a Network Engineer Career Roadmap divided into four phases:
- Phase 1: The Fundamentals (OSI Model, IP Subnetting, Basic CLI).
- Phase 2: Switching & Routing (The "bread and butter" of CCNA).
- Phase 3: IP Services & Security (Making the network smart and safe).
- Phase 4: Automation & Programmability (The future of the role).
