This repository documents my hands-on networking learning journey — from ** fundamentals** to production-level network configuration and troubleshooting.
It includes configuration examples, theory notes, and command references for key network technologies.
- Production Networking Scenarios
- Switching Concepts
- IPv4 / IPv6 Addressing
- Subnetting & VLSM (Variable Length Subnet Masking)
- VLAN Configuration & Trunking
- Spanning Tree Protocol (STP)
- EtherChannel / LACP
- Static & Dynamic Routing (OSPF, RIP, EIGRP)
- DHCP & DNS Setup and Troubleshooting
- Cisco Packet Tracer / GNS3
- Cisco IOS CLI
- Linux Networking Commands
- Wireshark for Packet Analysis
To build a strong foundation in network engineering , and to document real-world configurations for routers, switches, and Linux-based network systems.
