Hello, thank you for your response. 

Sorry, I wrote incorrectly. All IPs are in the 192.168.10.0/24 range, and there is no configured VLAN.

Nsx-T version 4

I didn't understand the part that appliances VTEP. How can an appliance have VTEP?

It's a nested environment; I only have a single edge node and a single nsx appliance. 

I've attached some screenshots from nodes and hosts.

Thanks
