Thomas, Larry, Lucy, Maria, and Paul, Thanks for the discussion, and sharing the insight...
I'd like to get us on the same page on when VDP is needed and when it is not, please help if the following points are not correct? 1) If NVE and TES are in the same physical device - there is no external wire between them, then no VDP or VDP-like protocol is needed, regardless L2 or L3 is used. 2) If NVE and TES are not in the same physical device, but TES to NVE using L3 protocols only, there is still no need for VDP or VDP-alike protocol. 3) If NVE and TES are not in the same physical device, TES to NVE using L2, then VDP or VDP-like protocol plays important role for discovery and more.
