Learning CPT

To dive into network engineering, I decided to explore Cisco Packet Tracer through a series of projects. My goal is to build practical skills and gain hands-on experience. My approach involves finding networking project ideas on YouTube, watching tutorials, and then attempting the projects myself. If I hit a roadblock, I try to solve it on my own by Googling and checking forums. If I still can't figure it out, I’ll revisit the tutorial for guidance. I'm currently following a few great YouTube channels like PM Networking, TechGuru, and Jeremy IT—they've been incredibly helpful.

First Project

For my first project, I built a simple network for a fictional small business with two departments. This project was a great introduction to using Cisco Packet Tracer.

Learning Cisco Packet Tracer The initial step was getting comfortable with Cisco Packet Tracer. I had to learn how to navigate the interface, add devices, configure settings, and connect everything to simulate a real network. This process was essential for understanding how to set up and manage network equipment.

Steps in Creating the Network

1. Configuring Devices: I started by setting up routers, switches, and computers for each department. This involved assigning IP addresses, configuring interfaces, and ensuring that all devices could communicate with each other.

2. Connecting Departments: Next, I linked the devices within each department and connected the two departments. This step was crucial for establishing a functional network and testing connectivity.

Introduction to Subnetting and Subnet Masks While working on this project, I also learned about subnetting. Subnetting is the technique used to divide a network into smaller, more manageable sub-networks, which helps with organization and efficiency.

• Definition of Subnetting: Subnetting allows you to split a single network into multiple sub-networks, improving traffic management and network security.

• Explanation of Subnet Masks: Subnet masks help define which portion of an IP address represents the network and which part represents the host. Understanding subnet masks is key to designing effective networks.

This first project was instrumental in building my foundational knowledge of the Cisco Packet Tracer app, as well as of network design and subnetting, and it was only the beginning of my journey into the world of network engineering.

Second Project

My second project involved creating a network for a medium-sized fictional company with three departments. This project gave me a chance to build on what I learned in the first project and introduced me to VLANs.

Consolidating Knowledge of Subnetting and Subnet Masks : I applied my understanding of subnetting to design a more complex network. I created multiple subnets to improve network efficiency and manage traffic better. This reinforced my knowledge and showed me how subnetting can be used in larger networks.

Creating and Managing VLANs : VLANs (Virtual Local Area Networks) are used to segment a network into logical groups. This segmentation can enhance security and performance.

• What is a VLAN?: A VLAN allows you to group devices into separate logical networks, regardless of their physical location. This helps in isolating traffic and enhancing security.

• Configuring VLANs in Trunk Mode: I learned to configure VLANs in trunk mode, which enables multiple VLANs to be transmitted over a single link between switches. This setup is essential for managing larger networks efficiently.

This project was a significant step forward, diving deeper into network segmentation and management. Learning about VLANs opened up a new dimension of network design for me. I’m thrilled to see how these skills will come into play in future, more complex projects. The journey continues, with each step bringing new insights and challenges!

Conclusion

Working on these projects has been a great learning experience. I've gained practical skills in network configuration, subnetting, and VLAN management (AND, I'm really starting to like it, the Cisco Packet Tracer app really is a gem of an app to learn Networking). My next project will be even more ambitious, and I’m excited to continue expanding my knowledge and skills in network engineering.
