Hi Greg, Yes this captures what I was trying to get added.
Perhaps the last sentence can be changed to: "This document is written assuming the use of VXLAN for virtualized hosts and refers to VMs and VTEPs in hypervisors. However, the concepts are equally applicable to non-virtualized hosts attached to VTEPs in switches."
