You are just amazing Mike. Most simplified explanation possible ❤❤

[trevspires]

Ur my hero - Sending this one to my customers FOR SURE.

Possibly the most simple explanation of overlay networking that I have ever seen in 15 mins.

[hamzasalahuddin]

Thank you so much for explaining it from a VMware Admin perspective as it was easy to grasp it.

[bakeruk]

Very well explained, especially the comment around a Layer 2/3 device only being concerned with certain fields in the ethernet packet. Nicely put!

[jorgeabalo]

[Prasanna_kul]

This was a great explanation. I am not a network engineer by any stretch. My speciality is Virtualization. The overlay and underlay terms have been very confusing to me. I could never figure out how I could specify a segment in the NSX overlay and the network SAs not track me down and slap my hands.
So correct me if I am wrong. What I took from your explanation is the edge VTEP IP is what the physical network is using at L3 for the packet IP header when routing out?

Man you are amazing... very well explained

Hi, im not from network background but this explained me much better about overlay network with GENEVE. Got a question. When orginial packet of Data, Innner IP and Inner Eth Header is wrapped by GENEVE header for encapsulation and VNI id is generated then how would the outer IP will find the destination TEP IP to pass the data along with the other Eth header to find the destination mac address of the host?

Had a solution architect wanting to run a MetroCluster and use NSX to replace OTV. I asked what will stretch the management L2 Vlan. He said NSX. I said you don’t put your management and run your vCenter and controllers on an overlay

Firstly... Mate, your vids are amazing and I'm a big fan of your One question though, is there any way to encrypt traffic in NSX? I always thought the encapsulation was encrypted but I'm finding out it's not... i.e. the separation between customers really needs to be encrypted E/W if you have multi-tenancy. Thoughts?

Hey Mike: I am starting with nsx now. I actually come from a physical network background.
Do you have any videos to spin up a nsx lab end to end ? Right from spinning up a esxi, Vcenter and nsx.? I know you have a nsx demo, but for esxi and vcenter ? Like a step by step video to set up in my lab or something.

[maxbriet]

hello,
Thx for your video
just to be sure If I understand correcty the overlay network is internal to nsxt component
if I try to contact a server on my physical network the "external world" don't see the geneve encapsulation just the classic exact?

Hoi Mike, Can you do something about VPN within NSX-T?

[hoanbui]

Hi sir, Can I ask you some question about LB on NSX-T?
