The Best Cisco Instructor of All Time, Thanks Kev for sharing Knowledge!

[aldebeer]

Thank you Kevin for your great arguments in your training, thank you for the way how you the subjects/title explain without going into the contents !!! The bottom line is; you are a great teacher.

[hatemnegm]

The best Cisco Instructor ever, Thank you very much

[dlpyfnc]

when i want to learn something on a thorough level, i always look for your "deep Dive" videos. thank you very much Kevin, you've been helped me a lot through my IT career.

[TheUrbanGeekinTECH]

As Always, Great Video :) Thank you Kevin!

[AnoopKumar-vebf]

Great one . Was wanting to learn this for long

[rpinto]

Thank you, Sir, for the time and effort that you have put in to making this video. This is by far the best video out on YouTube which explains the topic in depth.

[nicomifi]

After watching KW deep dive sessions you immediately go from Tier 1 to Tier 4 Engineer, Great video again Shifu Kevin

[KRICHAN_Technologies]

Great topic for the era we are moving into the tunnels world with sdwan. Thank you

[mostafaomar]

Thank you very much Kevin you are the best.

[noshut]

In the first example, is ospf required to be running on all four routers in order for the tunnel interfaces to be able to reach each other

Hi Kevin, first class presentation as always, but shouldn't the focus be on route-based VPNs relying on IKEv2 ( VTI, Flex-VPN ) ?
Crypto-Maps as well as IKEv1/ISAKMP based solutions are considered deprecated by CISCO...

[melvinoxl]

Great stuff. 2 questions:
1. With the advent of high speed broadband at cheaper cost, do you think dmvpn is becoming more popular compared to mpls and will mpls be confined to Service providers?

2. Do you think the industry will fully embrace sd-wan?

[Juventino]

Even it was helpfull I was missing a lot. For example which Technology is behind the sdwan Software how do they Connect to each side? Is there also a VPN behind? VPN policy based vs route based was missing too. This was more a VPN introdution then a deep dive but still interesting, thanks!

[petephelp]

Scheduled my ccna for the 24th I've watched all your deep dives feeling super confident about the test after so much preparation. Thanks Kevin!

[roscocsa]

This gives me flashbacks to a 3000 concentrator I inherited in the early 2000s. It fed the central network through a p2p T1 That was up roughly 24% of the time, and outside users accessed it through a painfully slow cable modem with a static ip. If I remember correctly you could get a whopping 112KB down over that link, upload was basically nothing. God I hated that T1. WV, early 2000s, not the best copper on the poles.

[DhrubRajGiri]

please also lunch the vpn courses in udemy

[jimboelterdotcomm]

I feel as if I finally have a handle on GRE over IPsec. Thank you!

[robertw]

In your .pdf guide for GRE. R1 & R2 have the same IP address
