What you will learn

OSPF Concepts and Theory

Configuring OSPF

Verifying OSPF operation

OSPF on Cisco Routers

Description

OSPF , or the Open Shortest Path First protocol, is the most common interior Routing Protocol in Networking. The only other protocol that comes close is IS-IS, and that protocol shares many of the fundamental concepts with OSPF.

Understanding the full depth of OSPF will help you:

  • Pass Certification Exams (CCNA, CCNP, JNCIA, JNCIP, etc...)

  • Conquer Job interviews for Network Engineering positions

  • Succeed and Excel in Network Engineer roles

This course is a modern, practical training series covering the full scope of OSPF. The stated goal of the series is to take anyone with a basic understanding of Networking and Routing, and make them a competent OSPF engineer.

The course will cover the most important (and most confusing) parts of OSPF:

  • OSPF Areas

  • OSPF LSAs

  • OSPF Neighbor Adjacency States

  • DR / BDR Operation

  • OSPF Metric Calculation

  • OSPF Network Types

  • OSPF Area Types

  • OSPF Configuration and Verification commands

The course focuses on practical training -- most of the lessons involve configurations and demonstrations for the concepts that are taught. 

There is particular emphasis on teaching the difference between verifying a devices configuration vs a devices operation. Every competent engineer must understand the difference between these two items.

The main thing that sets this course apart is the simplicity in which everything is explained an illustrated. You will be hard pressed to find better explanations of all the various OSPF concepts above.

Excellent course and really liked the way information was presented in a more practical manner versus just doing theory-based knowledge sharing. Looking forward for more such courses from same instructor.

Couldn't be explained better than this. All topics are on point. Great presentation and the Information is easy to digest the way he delivered it. I wish there could be more such as redistribution from other Dynamic routing protocols, prefix-lists, and OSPFv3. Overall, I'm satisfied with the content and learned a lot. Looking forward to more courses from you. Thank you, Ed!

I think the course is really great. Presenter is easy to understand and well-explains the key takeaways from each lesson. I like the YouTube links to go watch a supplemental video as well. The only item I would suggest is to have a better materials packet for all commands and abbreviations for quicker reference throughout the course and to use when practicing on your own. If it is available, then it was not clearly marked that I found it. Thanks!

Wow! Ed is an amazing teacher, I would say one of the best. Just like he said, his instructions are no nonsense and spot on. Thank you David for doing the course with Ed. I have to say I feel like every word is getting into my head after a long time. The last time I experienced this was sitting with my kids to listen to Sal Khan's instructions. Thank you Ed!!

Hands down the best course for OSPF! Loved how visual it was and also loved the fact that Ed not only covered its topics but also went into hands-on demonstrations as well! Would definitely recommend to anyone who are unclear about OSPF!

Ed, you deserve more than an accolade. The explanations were on point, and everything became clear as I progressed. Kudos to you, Ed. I must acknowledge that you are more than a network expert.
