4 21 Leaf:Spine Design MSDC 

getting back to networking after being out since 2018.... this is amazing!

Less than 1 min in and I can tell this guy knows his stuff and can explain it. Well done.

What a great explanation. I have seen a lot of videos, but just now, I understood the real differences between Collapsed-Core and Spine-Leaf Architectures.

Couple of takeaways I got from you are 1. VMs can be moved across different leaf's keeping the same IP address within the same VLAN. It utilizes the VxLAN technology Underlay and Overlay - Underlay is IP Routing and Overlay is VxLAN using VTEP's communicating with each other. Thanks a lot Terry !!!

This is a superb video. I've seen other people try to explain this 10x as long and not manage it.

Great video you really explain the leaf-spine design and make it easy to understand.

I really tried to learn something from this video but I can't focus on anything other than how impressively this man writes in reverse

brilliant. great refresher. thanks!

Great video, thank you!

great video!

crystal clear!!!!

Helped me very much.THank you!

Great video!

Thanks for simple explanation.

Great 👍 please why it not recommend to link spine switchs between them ? Thank you

I do some instruction at a local community college, what is the presentation software the lets you be behind the virtual white board?

Are you that good at writing backwards or is there some magic going on here? Great video and very unique presentation!

where can i get the full series ?

Hello! I have one question about spine switches. Are they connected to each other with stacking or any redundancy protocol like vrrp/hsrp?

How are these guys able to write backwards??

great Video ! How do i access other series ?

this is CCNP Level >D
