This man will be remembered as the one which simplified the CCNA to networking newbies 😉 Thanks a Lot!

I worked for an ISP for some years.

Leased lines usually don't use HDLC/PPP anymore, as the technology is way too slow for most companies needs.

They use QinQ (double dot1q tagging) to tag all your traffic with an extra vlan tag (called the service vlan). This allows lots of fast leased line connection (10g+) over the same infrastructure, and the ISP doesn't have to worry about vlan leaking or mismatches.

This also solves problems with several companies needing p2p trunk link transits over same infrastructure/datacentres, as all your traffic, untagged or tagged, will just be tagged with an extra vlan id over the ISPs infrastructure. The extra vlan tag will then be removed as the traffic reaches the other end of the leased line.

This basically solves the same problem in leased lines, as MPLS solves in internet connections: being able to use the same infrastructure without mixing customer traffic.

The ISP i worked in was quite small, and they had used this for over 10 years when i started.

This is in Norway btw, I'm not sure what standards are in other countries.

Although I have been practicing security for a few years and having been forced to learn networking basics as a pre-requisite. I started this journey with a paid course and then I ran across the king of ccna teaching. He has methodically introduced each topic in such hiearchy style while also making it appealing, exciting, and most of all with simplicity! Hail to the King of Teach!

I passed the CCNA exam today and I would like to thank you Jeremy for helping me out through this course. Your videos are the best available resource on the internet for CCNA. You're amazing❤

[cnps]

Mr Jeremy, you would be mentioned as one of the people who participated in the success of cisco certification in his CCNA 200-301 module. Thnaks 4 all

[mthoko]

You helped me pass the CCNA five months ago, here I am now studying for my CCNP and still using these

[amirkhang]

Hello everyone i am about to take my CCNA Exam. I am very thankful to Jermey For such awesome Material.

[themistoclesnelson]

I think the "ignore things you have never seen before" is some of the best CCNA advice I have gotten. Thanks Jeremy.

[DaviddX.]

Never stop my dude, you're saving peoples lives, thank you!

[papajohnscookie]

Just passed my CCNA today, I couldn't have done it without your videos and labs. Thank you for the great content.

[vileyogabear]

Thanks for the lesson Jeremy. After all the previous lessons the LAN and WAN architecture is where everything lines up. Everything just start to make sense when those little parts come together to form a network.

[damiancampbell]

Not gunna lie, replacing the entire MPLS service provider with a sudden giant switch was way funnier to me than it had any right to be.

[SeanTurner-xc]

I like the part at 13:03 where you put in a giant picture of a switch to represent the MPLS of the service provider

[ravisamala]

I saw old CCNA videos by Jeremy ceora and this latest course by Jeremy, both Jeremy's rocks, i like the way this jeremy explained the fundamentals in an simplified manner and along with the practise labs covering as much as he can. Best content delivered in an over simplified manner. kudoos to Jeremy and i am excited to see the CCNP level videos in a similar fashion. Once again thanks to Jeremy :)

[EsotericIntel]

When Jeremy says "However", you just know he's about to drop some knowledge.

[ravishelke]

content, presentation, thing is just awesome .👍

[Clovistered]

All I am going to say is now I know why people all over Reddit and different forms are talking about Jeremy, after watching few of your videos now I understand why you are so popular. Your explanations are amazing, to the point, but what impressed me the most is that each subject is not brought to us random, the subjects were carefully introduced one by one to paint the bigger picture, amazing work and thank you !

[abdous]

Finally After 2 months from following your course I'm up to date with you, I will start reading the official cert guide book and revise your anki card + notes that I took, and wait for your coming videos
Thank you Boss

[anitaghale]

Thanks to Jermey’s lab I learned a lot from your videos and I actually passed my CCNA today😅
Thank you so much 🤗🤗
Your courses are actually so much easy to understand 🎉

[patrikmansuri]

This has been clutch in helping me better understand the CCNA content in my DCOM class. Thank you Jeremy
