In this video we're going to take a look at EIGRP
Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco proprietary routing protocol although an informational RFC has been released.
It's an interior gateway protocol (IGP) meaning it been designed to be used within a single autonomous system. It's often described as an advanced distance vector protocol as it had both links state and distance vector like features.
EIGRP uses a three step process.
Become neighbours - Two routers running EIGRP form a neighbour relationship
Exchange routing information - The neighbouring routers send full update and then partial updates if any changes occur
Choose the best routes - Each router chooses the best routes to add to its routing table based route metric

I will NEVER forget what active state(lol) means in relationship with EIGRP! Excellent presentation 👍

[@Certbros]

Hahaha exactly! Thanks!!

[@Rockshoes1]

I can relate!!!

[@prospertombido921]

They sure know how to cater for all society lolx

[@pawann8061]

yeah:D

[@kbnumber24]

This dude is the best EIGRP explainer I've ever heard.

[@Certbros]

Thanks Bizzy B!

[@anonymously_me1803]

Right!

[@azurlake]

I almost fell off the chair. My kid is listening to this Old McDonald had a farm song when suddenly looking for an EIGRP configuration tutorial... BOOM

[@Certbros]

Hahaha! Love it!

[@rocksolid6582]

Love the visuals, my head spins when I read this from a text book. I can digest this a lot easier. Also glad that you break down the metrics for the protocols really nice to know

[@m.raflyyanuar9886]

You answered literally all of my assignment questions. I have to cite my references while your video covers all of the questions asked. Amazing video!

[@boffyrox2]

@CertBros: Please continue to make more of these videos, and if need be create a Patreon. These are extremely simple, well thought out, and clean for the end-user experience. I haven't seen a new video in 5-months, and would love it if you continued to make more when time permits. Thanks!

[@Certbros]

Thanks A J! I'm working on a bunch of new videos.

[@realshady6172]

dude can't stress how hard you helped me do my exam. YOU'RE THE BEST !!!!!!

Hahaha 🤣

[@rollobeatz1671]

Same here it’s how I memorized this 😅

[@yannicundminecraftlp]

It is a mess XD E I G R P

[@hamzasalahuddin]

Thank you so much I was really struggling to understand FD & RD along with how to calculate Metric, so with the help of this video my concepts are much clearer then the day before when I started to study EIGRP. Awsome channel!!

[@Certbros]

Thanks Hamza! Good to hear it helped you out

[@niksta007a]

Brilliant.. watching all your quality vids as a refresher! So many thanks for making these!

Thanks for the comments!! Glad you like the videos. More are on the way.

Cert bros. Can you guys please put out more videos on a consistent basis. I would pay top dollar for your videos. I've yet to come across videos as clear and precise as these. Please let me know what you have in the works. I feel that I can learn anything as long as I see that blue background.

[@Certbros]

Wow thanks man! Working on the rest of the CCNA topics. Will try and get these out as quickly as possible!

[@pled8395]

Even as a CCNA R&S, this channel refreshes my mind in an instant when I'm in doubt about something!

[@Certbros]

Thanks! Good to hear they still help you out.

[@wmuhken]

Excellent presentation, I especially loved the route advertisement using the home inquiry example it made it so easy to understand

[@Certbros]

Thanks Wilfred! Glad you liked it!!

Your explanation is on par dude.

Cheers!

Thanks Addison. More videos coming soon

[@cyrushurley2351]

Solid explanation! I just finished my CCNA course and am taking practice tests. Now I actually understand what EIGRP does LOL.. PS I liked the neighbor analogy.

[@lenso2010]

Indeed as expected I am from my Networking exam. I just recalled old MacDonald and it all came in. Thank you

[@Certbros]

HAHA LOVE THIS!

[@ZekeKhirbash]

What an awesome channel to learn or refresh some of Cisco's networking technologies & solutions!!! One question though, the subnets don't have to match between the two neighbors. I tried it in a lab environment and was able to establish neighbor relationship between two peers.

[@SM-wt8gd]

Your videos are fantastic. Concise, clear, and very well presented. Thank you for your work.

Thanks Marawan!

[@qaisahm8144]

I'm still confused about the 100 delay. Why is 10 microseconds used instead of 100??

You really deserve more subscribers, this is excellent stuff. Thanks for sharing your knowledge!

Thanks Sam! Fingers crossed we get to 100k this year! 🤞

[@Certbros]

Thank you!

[@LDARSHAN1991]

This is a great explanation of EIGRP. However, I would like to inform one thing that is not clarified in this video is that there is a difference between FD (feasible distance) and CD (computed distance). When we get RD (reported distance) from the neighbour and add the metric value to reach the neighbour it will provide the CD and not FD. The least computed distance route(s) become the successor route(s) and its CD is considered as FD.
