Free CCNA | Dynamic ARP Inspection | Day 51 | CCNA 200-301 Complete Course 

ERRATA: At 5:11, the Src MAC of the GARP should be PC2's MAC.

we almost done with the course boys

Recently got a really good paying job in networking and I could not have done it without these videos. Experience is limited but passing my CCNA using your course helped opened these doors for me. I feel like I owe you part of my salary lol As long as these videos keep coming I will keep watching! Thanks again Jeremy!

I am revising for the 3rd time the whole series. You made me a Network guru 2 yrs ago. The concepts gave me a very strong background even with cloud networking.

Hi Jeremy, you made the difficult topics so easy to understand and I watched all your videos so far and was able to pass my CCNA exam today! I could not have done it without your video series.

Jeremy, just wanted to say thank you for all your lessons. I passed my CCNA exam a couple days ago thanks to you and your videos! So, thank you again for all you do!

The best teacher in the world! Thank you,Jeremy.

hey, Jerry ...this is the first video I watched on your CCNA playlist. And it's extremely effective and useful. You explained everything in 30 minutes. I really appreciate you making these high quality video available freely on RU-vid.😀

Sir, you are an inspiration for me. I would like to help people, like you are doing now. N.B. in our culture we address teacher as Sir. I am from Bangladesh.

Thanks J always grateful for the knowledge you share. Bless

many thanks to teacher Jeremy, a great teacher, every lecture is well designed, in depth, detailed explanation on command information.

Hi, thank you very much Jeremy for your great lessons. Today I finally passed the exam with 932.

Awesome teaching style.. Thanks a lot for supporting us

You are very great teacher for CCNA course. Keep it up From Oromia.

Great closer to the end of the security topic. God bless u sir

Thank you for the video. You are a great Teacher :).

I passed CCNA today and scored 941 But I still love to watch jeremy’s videos I don’t know when I will get the certificate?

Jerremy how many more days (videos) to finish the ccna course ?

Great job with this series... Do you think you will do a CCNP series? If you do, and it's anything like this CCNA... There's no doubt it will be at the top of the courses list!!!

Another great vid,Thank you.

Thanks! Jeremy!

Thank you so much, Jeremy.

Thanks 💛

Thank you Jeremy

Thanks!

Thanks for the video Sir!!!

Dear Jeremy, I want to start my CCNP studies and you have mentioned dozens of time that boson is a very good studying resource and I can see why. But I don’t know exactly which one to buy. I think boson netsim is a good choice, as I can lab CCNP topics and recall CCNA topics as well. Please recommend one. Thanks!

Good teacher

Hi Jeremy, first off i'd like to thank you for all the work that you have done for the CCNA and the current work on the CCNP it really motivated me to completely change my carrier perspective. Secondly, could you tell which software do you use to make those schematic i feel like you take a screenshot from GNS3 then add arrows or checkboxes and then bring everything inside a powerpoint that you present on the video, am I right ? Still thank you and have a nice day

Thank you

Does ARP poisoning by using a default gateway affect routing protocols? Probably not right since a pc would not be connected to two routers?

I think DHCP snooping enabled globally to allow arp inspection and ip source guard to use its table.

Hi Jeremy! Do you use Wendell Odom books when preparing your videos? I want to understand if I should read his book?

hello dear. would like to educate me how the MAC address of the routers will be known to each other while routers exchange packets between each others if ARP is meant only within LAN, because packets have to apply layer two encapsulation .

Amazing content!

a very minor point: @ 12:39 dhcp is mispelled in the second line, although it's clear what it means

Hello, Jeremy. If I learned all the videos that you've posted. Am i good to go for the CCNA exam?

Great series

Jeremy I fell in love with you!☺

Hi Jeremy, i have a question here about DAI optional check at 16:00 with also that example. DAI won't check the message on trusted port, when PC1 send ARP request to SRV1 and SRV1 send response, the ARP response won't be checked on SW1, right ? How is the optional check work if the ARP response won't be checked ? Or maybe when we configure the optional check, the ARP response will be checked ?

hi jeremy for quiz 3 when i use ip arp inspection interfaces i see rate. and burst interval for the trusted ports also can you check so for that case the answer should be thats its enabled on all ports. i know it doesnt filter trusted ports but i am not sure about the rate please let me know

Hi Jeremy! I configured everything but when I connect another PC to SW1 the PC can send pings to anyone without being blocked by arp inspection. How do correct this? What did I do wrong?

@Jeremy's IT lab when they ask to define explain give the characteristics of certain concepts does that mean we should be writing them down or it's multichoice questions only

thanks alot

Hi Jeremy, I have an inquiry Do we need to config DHCP snooping to be able to use DAI?

Hey man, I enrolled in your lab course and I’m about to buy the other course. What’s the advantages of the website course vs RU-vid vids. Will this course properly prepare me for the CCNA or get me close enough to pass?

Plz upload the lab vedio as well

loved it :)

So the switches don't inspect traffic on untrusted ports going to the device? Only those leaving, correct?

Could you please make CCNP tutorial

Does anyone feel that you're forgetting the previous videos after some new learnings 🙂

Hello Jeremy, how many days are left?

10000000000000000 Thankxxxxxxxxxxxxxxxxxxxxx
