This repository contains a collection of networking labs and configurations created using Cisco Packet Tracer.
Each project focuses on different networking concepts such as LAN, VLAN, Routing Protocols (RIP, OSPF, BGP), ACLs, DHCP, SSH, VoIP, and more.

These labs were built to support my learning and practice in network engineering and cybersecurity.

• Single & Dual LAN – Basic network setup using static IPs and router-based interconnection.
• VLAN & DHCP – Network segmentation with dynamic IP address assignment.
• Access Control Lists (ACLs) – Traffic filtering and access restrictions.
• Routing Protocols:
  • RIP (Routing Information Protocol)
  • OSPF (Single Area and Multi-Area)
  • BGP (Border Gateway Protocol)
• SSH – Secure remote device management via CLI.
• VoIP – Voice over IP telephony setup with DHCP and telephony services.
• Static IP – Manual IP addressing for network devices.
• HTTP Server – Hosting and accessing a basic HTTP service within the network.

• Configuring Cisco network devices using CLI commands.
• Static and dynamic routing configurations.
• Layer 2 (Switching) and Layer 3 (Routing) networking concepts.
• DHCP for automatic IP assignment.
• Implementing secure remote access with SSH.
• Setting up VoIP telephony services.
• Building and testing real-world topologies.
• Analyzing packet flow and troubleshooting connectivity.

• Cisco Packet Tracer
• Cisco Routers (2811 / 2911 models with telephony capability for VoIP)
• Cisco Switches (2960 series)
• PCs, IP Phones, and Servers

1. Download the .pkt files from any lab folder.
2. Open them using Cisco Packet Tracer.
3. Review the .txt file for configuration commands.
4. Check the .png screenshots for expected outputs.
5. Modify and experiment with the labs to strengthen your understanding.
