Does latest NSX support STT and GRE for overlay? I saw them mentioned in some old NSX articles while searching on Internet but didn't find setting about them now.
if you ask about NSX for vSphere 6.1, the answer is no.
Does VMware explain why they drop STT and GRE support?
VMware did not drop STT/GRE
In NSX we have two different flavor of NSX
NSX-MH (Multi hypervisor) and NSX-V (vSphere).
NSX-MH support STT, GRE, VXLAN
NSX-V support VXLAN
Is that make sense?
what's the difference? different target audience? VMware doesn't seem to emphasize there are two versions on their official NSX page.
