In this video we're going to take a look at OSPF.
Open Shortest Path First (OSPF) is a widely used and supported routing protocol.
It's an interior gateway protocol (IGP) meaning it been designed to be used within a single autonomous system. It also falls under the category of Link-state routing protocols.
Routers running OSPF learn about the enter network in order to create routes. They do this by flooding Link State Updates. There are three steps to the process.
Become neighbours - Two routers running OSPF on the same link agree to form a neighbour relationship
Exchange database information - The neighbouring routers swap their LSDB information with each other
Choose the best routes - Each router chooses the best routes to add to its routing table based on the learned LSDB information

The official Cisco coursework for this topic is so wordy and obtuse I really must thank you for posting this video. You explained in 13 minutes what Cisco failed to explain in 15 minutes and several pages of dense acronym-laden text.
You are the real MVP
Thank you! Sometime it just takes a different point of view to get a good understanding.
@@Certbros Exactly. I have my CCNA exam and still struggle with some things. Meaning that I am not going back to those Cisco texts :((( Thank you. It was short and precise.
@@Certbros i
Thank you! I love you videos, clean and simple to understand. There's only so much reading I can take in a sitting! 💖
Haha! I know the feeling!! Thanks
This explanation is so simple and clear you can easily understand even if there are a lot of terms to remember. Awesome tutorial!
This video was absolutely phenomenal! And the joke at the end was priceless.
Haha! Thanks Darnell. Glad you liked it.
I love his explanation on OSPF and Spanning tree protocol!
Thanks Birara!
I've watched about 3 videos regarding the same topic and this is the only video/animation that actually made sense. Great job at explaining a difficult topic in such a simple way! I'm impressed. Thank you!
Glad the video helped Victor. This stuff can get pretty confusing.
This is the most useful and explanation of OSPF, that is absolutely unbelievable for 13 minutes video. Every word said bears only important information and nothing superfluous, especially rooter =)
Simple the best! Clearly and helpful videos! Thx CertBros!
This is what I call effective knowledge sharing. Very easy to understand. Keep up the good work.
Thanks Vimukthi!
thanks mate, this visual step-by-step explanation has been so valuable
glad that you are back. some of your videos helps getting my CCNA
Thanks man!
Best explanation video that I've seen so far. Good job.
Thanks!
Read a lot of recommended books on this topic and also watched a lot of videos.. This one has stuck with me for its simplicity and how well you explain the protocol.. Using some cisco white papers to lab this up in EVE-NG and referring back to this video gave me my "Aha" moment... Great stuff on the channel keep it up.
Really glad to read this helped it click for you! Keep up the great work Marcais 🔥
Brilliant. THANK YOU SO MUCH for this well illustrated video. love it and became a big fan.

Amazing way to explain OSPF step by step
Thanks
YES YES YES Thank U!!!!
Well, this is a perfect background to see how dirty my monitor really is...
This color is also best for checking if monitor has dead pixel
Same here. That blue background came up and I said, "Oh yeah, I smashed a fruit fly there a month ago."
Beautifull animation. Can i know what is the software to build it? Thank you
Very well illustrated. Thanks mate
No problem!
so simple and so clear thank you
No problem!
Thank you. I’m going to watch this a few more times until it completely clicks.
Good luck Edward. You'll get it! 💪
Awesome eggsplanation guys. Nothing beats the end of the video though :).
Love it love it love it
Thankyou nicely explained
awww a lil bit too late cuz my OSPF quiz was 2 weeks ago.. lulz nevertheless, really appreciate it. It's much, much easier to understand OSPF from your video than reading thick-ass CCNA/CCNP books
Ah man! haha. Yeah those books can be challenge at times. Glad you liked the video!
It was a great informative video that can help in answering cisco exam questions. Thank you. BTW, we all know rowter or Rooter...at the end of the day it is ROUTER :)
Its pronounced ROOTER 😂
@@Certbros C'mon, y'all add a 'u' in honour and colour but take it out in roUter? ;-)
Thanks for the video, networking is a *lot* of information, and some of it is pretty dense until you unpack it and wrap your head around it...this vid was easy to understand!!
Explained better than my professor at university managed to do. Thanks
Happy to help!
Am liking every comment here because certbros is really teaching good stuff here . nice channel
Thanks man!! Keep those likes coming!
Awesom video, in future if you are adding any no like part 1,2,3 then it would be easy for me to see the new uploaded videos one by one

Great video!
Thanks!
