Thanks Bizzy B!

[@anonymously_me1803]

Right!

Hahaha exactly! Thanks!!

[@Rockshoes1]

I can relate!!!

[@Certbros]

Slight over exaggeration but thank you anyway! 🤣 Glad you liked the video 👍

Check out Professor Messer.

[@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.

[@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.

[@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.

[@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!

[@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!

[@niksta007a]

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

Let's us know when you pass!

[@flacostarr]

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!

You're awesome! My teachers don't do their job as they should be but thanks to you i learn lots of things.

[@Certbros]

Thanks Gabor! Happy to help.

Thanks Hamza! Good to hear it helped you out

[@SM-wt8gd]

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

[@Certbros]

Thanks Marawan!

[@marcin5272]

... got slightly confused with a successor and a successor route? Isn't there a mistake (14:20)? I thought the successor was the next-hop router for the successor route and the successor route was the route with the lowest metric to reach a destination. If so, then there is a mistake in your explanation. Am I right?

[@JuryOwenClavio]

thank you for this material...its been a very good help! 😃😃😃

[@EM-do1yi]

🔥🔥🔥 easy to understand and the subliminal comedy and bleeped cursing is awesome lol!!!

[@yumenokira7595]

how good are your videos ? Well i've been through 3 mins of this one and i paused so i could hit that subscribe button...that's how good. You do not give a linear boring as fuck lecture of the subject that's how good it is. A little bit of you humour to digest the information, some cli commands display so we get a glimpse of what it looks on the field...that's how good they are! keep up the good work please

[@avanox3100]

thx man ! (was a little forgotten ) thanks for explaining so well!

[@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.

[@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.

[@aeromaxout]

Probably the best video on youtube.

[@Certbros]

Thanks!!

Thanks! Good luck with the studying and let us know how you get on!

[@raulsanchez4716]

Thank you so much! Amazing explanation. Your examples were pretty funny and clear to understand.

[@Alestrix76]

How can a router calculate the new metric when it knows only the RD from the adjacent router and its own bandwidth and delay to that router? How would it know what the least bandwidth is? How does it know the other delays? Shouldn't those (from the other router's perspective) also be sent down the path?

[@Certbros]

Good question! You are correct. The lowest bandwidth value is also sent.

[@freshslaya]

Your content is very good. Used it to pass my CCENT and will use it for my CCNA as well. Keep up the great work.

can you please explain how the routing loop can occur if FS's RD is higher than successor's FD ?? cz the best route will always be through successor and if in any case successor goes down then the traffic will go though FS

[@Hitman305505]

Are you going to add more video about Eigrp?

[@zuliano05]

Why the reported distance received for that router must be less than the feasible distance calculated locally to guarantees a loop-free path??

[@Certbros]

If the reported distance is more than the current feasible distance, this could mean the route has looped back through the same routers. This link should help. www.cisco.com/c/en/us/support/docs/ip/enhanced-interior-gateway-routing-protocol-eigrp/16406-eigrp-toc.html#anc8
