Welcome! I’m Jahson Jno-Baptiste (JB) — an IT professional and veteran, building my way into network engineering & cybersecurity through hands-on labs.

This repository is my hands-on CCNA portfolio, showcasing:

• Configuration skills (switching, routing, security)
• Troubleshooting ability (broken → fixed labs)
• Documentation habits (configs, screenshots, markdown)
• Network design (home lab with pfSense)

• VLAN & Inter-VLAN Routing
  Configure VLANs, router-on-a-stick, and troubleshoot common issues.

• Static & Dynamic Routing (OSPF focus) Showcases subnetting, route advertisement, and path selection.

• ACLs – Traffic filtering and access control.
• NAT/PAT – IP translation for WAN/Internet access.

• Troubleshooting
• Intentionally broken labs to demonstrate diagnosis + repair process.

• Home Network (pfSense-based)
  Realistic design with segmentation, DHCP/DNS, and firewall zones.

✔ VLAN segmentation & trunking
✔ Router-on-a-stick inter-VLAN routing
✔ Static & dynamic routing (OSPF)
✔ ACLs (standard & extended)
✔ NAT & PAT configuration
✔ Systematic troubleshooting (ping, traceroute, show/debug)
✔ Network documentation (configs, diagrams, markdown notes)
✔ Firewall + home lab design with pfSense

Employers don’t just want certifications — they want proof of real-world, hands-on capability.
This repo shows:

• Configuration fluency (raw configs + guides)
• Troubleshooting process (broken/fixed labs)
• Documentation habits (markdown + screenshots)
• Initiative: building labs without physical routers/switches

📌 Built with GNS3, VMware, VPCS, pfSense, and open-source tools.

Each lab will also be published as a Medium article (300–600 words) with:

• What the challenge was
• How I solved it
• Screenshots & configs
• Reflection on what I learned

📎 Published so far:

• VLAN & Inter-VLAN Routing – My First CCNA Lab in GNS3
