The only downside to now having my CCNA is that nobody else teaches as well as Jeremy, and the CCNP course is far from complete :D. IDK what to study now! Thank you for all you do Jeremy :)

Hello Sir, I have completed half of CCNA, Really interesting & I’m learning a lot of information. Btw I’m switching from Mechanical Engineering Background to IT Field. This is because I got a confidence from your videos.
After finishing CCNA I will be there for CCNP ENCOR…
Thanks for helping future IT aspirants like me. 🙏♥️♥️

[jcoley]

Excellent explanation of MTU. Well done and thank you!!!

[zeko-power]

I'm so desperate for your new video release comes up with new knowledge & skill. Sir much more respect and love

[Shubham-Mishra]

Currently studying CCNA with ur course and then will go for CCNP.. thanks for the videos Jeremy... ❤️

[yatinsadhwani]

Happy to land here while searching for MTU. Really appreciate Quiz section. Thank you for all the efforts! :)

Question 2 in the quizz is asked in a clumsy way. It took me a while to work out the question.
Better would be:
Whic (2) answers below are benfits or disadvantages of using Jumbo Frames.

Top notch video as always,

[ChristisKingEver_]

Passed my CCNA Thanks to you and Neil. Coming for my CCNP. Any job role/ path recommendations?

[mesfingudeta]

Dear Jermy, you're an amazing teacher;Please prepare more ccnp videos included in 350-401 and provide us!

I appreciate the insights shared in the video, but I would like to clarify that the Jumbo MTU is typically used because it supports 1G and faster connections. It seems there may have been a misunderstanding regarding this point in the video. Thank you for your efforts in creating this content!

Thank you for taking the time to do those videos, i respect what you are doing for us 🙏

[damiannaziomek]

Great explanation abaut MTU with GRE tunnels :)

[kangkang]

Thanks a lot to understand this mtu currently was doing about jumbo frame for AV over IP

[preetidongave]

You are just awesome!! Great lucid explaination!!!

[specific_pseudonym]

One big thing to remember: Some networking hardware will fragment tunneled packets even if those packets have the DF bit set, so long as the packets aren't larger than the physical MTU, because many such devices don't keep the idea of tunnel MTU in mind :( Meraki is one such example.

On a related note, actual tunnel-encapsulated traffic often DOESN'T have the df bit set, but will fail to be decapsulated in the event that the tunnel packets are fragmented. One example of this is the Sonicwall GlobalVPN client, which does NOT perform path MTU discovery :(

[mudasir]

as usual full of information...well explained!

[domingoalvarez]

Hello Jeremy I am seeing that the videos you are uploading are not the ones covered on the exam guide.

[daimon]

Great videos! I recently passed my CCNA exam! Jeremy have you considered doing CCNP Security videos?

[balintmucsanyi]

Great explanation, great video. I have a question, at 24:48 before reloading you don’t need to copy the running config to startup?

[TheBeach]

Looks good. Will the CCNP course be complete soon?
