I would change the introduction to the following to mention the use of



   "Virtual eXtensible Local Area Network" (VXLAN) [RFC7348] provides
   an encapsulation scheme that allows building an overlay network by
   decoupling the address space of the attached virtual hosts from that
   of the network.

  One use of VXLAN is in data centers interconnecting
  VMs of a tenant.  VXLAN addresses requirements of the
   Layer 2 and Layer 3 data center network infrastructure in the
   presence of VMs in a multi-tenant environment, discussed in section 3
   of [RFC7348], by providing Layer 2 overlay scheme on a Layer 3 network.
   Another use is as an encapsulation for EVPN [RFC 8365].

  In the remainder of this document the terms VM and End Station
  are used interchangeably.

   In the absence of a router in the overlay, a VM can communicate with
   another VM only if they are on the same VXLAN segment.  VMs are
   unaware of VXLAN tunnels as a VXLAN tunnel is terminated on a VXLAN
   Tunnel End Point (VTEP) (hypervisor/TOR).  VTEPs (hypervisor/TOR) are
   responsible for encapsulating and decapsulating frames exchanged
   among VMs.
