Free CCNA | WAN Architectures | Day 53 | CCNA 200-301 Complete Course

[@praisebetoyourCreator]

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

[@tikshuv-ccna]

True. Tremendous effort, script and digging makes this course incredible.

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.

[@JeremysITLab]

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.

[@kensrensen100]

@@JeremysITLab Yes, I thought they fulfilled the same purpose or were descendants of leased lines. Evidently, i was wrong then?

[@malkeetsingh]

@@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.

[@xunililak1674]

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!

[@shubhammoral5502]

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❤

[@MohammedAbdalla-d5g]

Wt resources did u use?

[@americanswan]

How useful were Jeremy's Labs?

[@cnps235]

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

[@JeremysITLab]

Thanks Abderahim :)

[@mthoko]

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

[@DaviddX.]

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

[@themistoclesnelson2163]

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

[@papajohnscookie]

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

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.

[@comraede]

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

[@kirollossaad6660]

I was just thinking that 😂😂😂😂😂

[@vileyogabear3183]

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.

[@JeremysITLab]

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 :)

[@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 !

[@EsotericIntel]

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

[@ravisamala87]

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 :)

[@ravishelke3581]

content , presentation, delivery................every thing is just awesome .👍

[@SeanTurner-x7c]

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

[@abdous6052]

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

[@kensrensen100]

34:30 you can also do the opposite. Check to make 100% sure the answer can not be either of the alternatives that you know.

[@joncents2000]

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.

[@fatimahamdan3825]

super proud to post the first comment lol thank you so much for this video !

I bought flackbox CCNA content but i still prefer to watch Jeremy because his explanation is way better than Neil Anderson.

[@majiddehbi9186]

Thx jeremy the end is close big hope thx and have Nice day

[@SirPeterlll]

I enjoy these videos more then the videos that has the cisco tool. Also DSL/Cable/Modem etc should be in lesson nr 1 in my opinion.

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!

[@AdventureRuss_AE]

Hey Jeremy, quick question, where can I find your video on PPPoE/PPPoA?

[@peppigue]

"...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?

[@JeremysITLab]

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.

[@jasonwestermeyer645]

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'm making the course in the order I think is most logical to study

[@jasonwestermeyer645]

@@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!

Deference between Internet and intranet?

[@JeremysITLab]

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.

[@tikshuv-ccna]

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.

[@SirPeterlll]
