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.
I guess you're referring to Ethernet connections (like Metro Ethernet), since you mentioned QinQ. I was referring to serial leased lines in this video, hence HDLC/PPP.
@@JeremysITLab I too worked with an ISP for almost 18 years and handled last mile connectivity. from Serial interface to OFC, serial is extinct as of today, I believe. its ETH all over and that too on OFC.
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❤
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.
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 :)
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 !
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

Now i know .....everytime i restart my company windows laptop, CISCO VPN pops up on the lower left part , now I know in my head how it functions. Thank you so much sir for the quality education that i can't get from school, truly amazing.
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 🎉
Are serial and DSL concepts being faded out of the CCNA? I just got questioned on those in a separate course I'm taking and just want to make sure I'm not going to regret it if I don't know the different protocols and what they do or how to configure them.
I have my test scheduled for November 5th Jeremy! Im so nervous and excited! Im scoring 920-950 on ExSim in simulation mode.. but I still dont know if Im 100% ready. I feel like Im memorizing the answers lol but I read the descriptions right or wrong!
Good luck Bobby! If you repeat the same practice exams you'll definitely start to memorize the answers so they won't be as reliable to measure your readiness, but they're still valuable practice!
No body cant understood what it means to mean to get those materials and tutors for me;Im from Ethiopia t really appreciate what you are doing ....its so much helpfull
so many videos on what vpns are and different hardware used in the functioning of the different types but no one ever starts with the big question. "why vpns?" thank you.
hi Jeremy, confusion at 5:20 shouldn't there be only 1 leased line from Data center to ISP since all sites are connecting to ISP ? or data center will have separate lines for each site office as shown in topology ?
I just looked for a playlist like this because I could not understand anything from my class starting with this lesson. I’m using this for the course final exam and the ccna.
Thank you jeremy for this great course , i was just wondering if your course have a sildes i mean the slides you explain on the videos it will be helpful to us if we can download it somewhere
So much information but it seems to shallow - I feel as if I don't know enough about each topic. Seems a bit ambigous and leaves so many questions unanswered ; however as you mentioned at the start of Networking jouryney, we are not expected to know everything in detail. Thank you for this amazing course sir
I hope one day you will make a video series for CCNA service provider certification. I''m curious to know what's happening on service provider's end. Anyway thanks a lot Jeremy for making this video. 😀
I have a question, physically the traffic will flow through the hub and eventually to the spoke routers using DMVPN? Is it just a logical tunnel which makes it look as if two spokes are directly connected ?
Thank you Jermy for those videos, could you please give me a link to the flash card and how to use it. you mention it many times and seems it an efficient method to study.
Thank you very much, the course is exhaustive and understandable even by a layman on the net. Can I ask you how many lessons are still missing at the end of the course? Thanks again
Thank you jeremy for this great courae , i was just wondering if your course have a sildes i mean the slides you explain on the videos it will be helpful to us if we can download it somewhere
Sir, please tell me How many more videos yet to come As I am attending for the exam so I need to fix end date I have started august 1 when total ccna videos were 99 thinking that's the end ....But now as it's adding up...I can't figure out end video please enlighten me with the left topics to be COVERED
The new CCNA test doesn't provide scores anymore. I took it this past Tuesday. I wish you would have started with the new topics such as Wireless, Orchestration, and Virtualization. I passed, but I know of the 15 questions on wireless I'm sure I missed all of them.
@@JeremysITLab I understand. It's just that most of this same training is provided by other sources. While I was training, I found it difficult to find adequate training on wireless, which is a LOT of the current CCNA. It covers multiple sections of the exam. My three week points on the exam were within Security (67%), Network Access (70%), and Automation and Programmability (80%). These are the newest additions, and wireless falls within each one. I would really like to see you do at least a two day course on Wireless because it cover so much ground. I'm looking forward to it, even though I've already passed the exam!
"...transparent to the customer..."? Don't you mean the opposite, opaque? That means the customer isn't privy to or need to be concerned about what goes on in transit/under the hood. Or am I missing something?
We use the term transparent because it is as if the customer devices are directly connected; the service provider's network is 'invisible', as opposed to a Layer 3 VPN in which the service provider's device are visible and are used as Layer 3 neighbors.
The Internet is a large global network...the one we're using to communicate now. An intranet is an internal network used within an organization, usually not available to people outside of the organization.
Also there is another one: Extranet - which means a net that gives access from the outside to the inside - for example: outside supplier of a company that needs access to a data of a company so the company gives access specific to the supplier - it similar to DMZ.
From my interpretation of the CCNA exam topics, my experience with the current version of the exam, and referencing other CCNA materials, it's not necessary for the current version.
This man will be remembered as the one which simplified the CCNA to networking newbies 😉 Thanks a Lot!
True. Tremendous effort, script and digging makes this course incredible.

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.
Had me in stitches for a good while! similar to the SOHO image from the ccna cert guide library 😂

Thanks Abderahim :)
I think the "ignore things you have never seen before" is some of the best CCNA advice I have gotten. Thanks Jeremy.
Never stop my dude, you're saving peoples lives, thank you!
You helped me pass the CCNA five months ago, here I am now studying for my CCNP and still using these
Just passed my CCNA today, I couldn't have done it without your videos and labs. Thank you for the great content.
Hello everyone i am about to take my CCNA Exam. I am very thankful to Jermey For such awesome Material.
Good luck!

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.
Thanks! That was my intention for these videos, and why I chose to put them toward the end of the course and not the beginning :)
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
When Jeremy says "However", you just know he's about to drop some knowledge.
