• 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.

• God bless you for this. really. ive watched so many videos on vpns and i couldnt understand shit they were saying. youre truly a blessing jeremy.

• tysm

• 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.

• omg, netscape…. wow that takes me back. lol

• 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.

• 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 ?

• Amazing lesson❤

• Redundant Internet Connections 17:15

• Lifesaver!!!

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

• Thanks jeremys for this wonderful video on wan.

• so a hub and spoke topology is a star for WANs

• Thank you so much Jeremy
  You make ccna very easy

• thank you sir

• 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 🙂

• 12:55 lmao I don't know why this was so funny

• 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

• 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!

• 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 !

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

• I was hoping for bgp >_<

• 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 ?

• 12:55 Big switch😂😂😂

• 6:02
  what is the diff between Enterprise & Service Provider ?

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

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

• thank you for all of your videos. They are amazing!

• 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.

• 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.

• Day 53. I made it. thanks for these videos.

• "…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?

• is this enough for ccna exam

• @Jeremy's IT lab I would like to get boson net sim software how do I proceed

• 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.

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

• Thank you so much!!!

• great stuff!!! thanks Jeremy

• Thank you much Jeremy ! It is awesome ! God bless you !

• 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!

• although it's just a basic introduction, it's very informative, very good.

• The best:))

• Thanks .

• In this video, google ads sens is showing about hair fall solution advertisement. What about your hair condition dear teacher?
