Course Description:

Knowing the fundamentals of L1, L2, and L3 Networking Protocols is vital to anyone who is in the networking field today, whether it be Application Service Provider, Network Service Provider levels or Enterprise level. This 3-day insightful and revealing course has been designed to focus on the systems approach, the engineering thinking, behind the world of Layer 1, Layer 2, and Layer 3 Networking.

Anyone working in networking today must be a master the essentials of these protocol layers, and this course will help you to accomplish that knowledge level.

This is an instructor led training (ILT) course that is usually held at a customer location or online with a live instructor.

The course is a combination of knowledge training, systems analysis, with hands-on exercises using Cisco routers and Cisco IOS, designed by CellStream consultants to bring the technician/engineer, who knows a about L2 switching, to a deeper understanding of L3 focusing on OSPF, BGP, Multicast PIM, and then VXLAN itself. A combination of knowledge training, hands-on exercises, and hands-on experience through execution of Command Line interface to Cisco routing labs reveals the L3 functions in a swift, detailed, and understandable way.

Course Objectives:

The objectives of the course are to:

1. Develop a “hands-on” skill set targeted at Layer 1, Layer 2 and Layer 3 methods and protocols
2. Learn how to use critical networking tools and methods
3. Improve student job performance by having a more complete and robust understanding of the subject matter
4. Improve customer/coworker satisfaction by sharing the knowledge and skills to work and troubleshoot the network
5. Deepen networking knowledge and understanding

These objectives are met by covering the necessary technical bases in a straightforward manner, by keeping the content in context of the objectives – connecting the dots. Utilizing a short, subject specific architecture with exercises to drive home key points and Hands-On experience that reveal these points builds skills and knowledge based on Bloom’s Taxonomy. Presentation methodology is industry current and up to date using a technology specialist.

Audience:

The target audience for this course is anyone in the telecommunications field that requires a solid and complete understanding of the fundamental operations of L1, L2 and L3 networking, especially new hires, and desires hands-on skills that can be applied to their job function. Ideal candidates are:

• Central Office Technicians, Engineers, and Supervisors
• Line Technicians, and Customer Service Technicians
