Re: [bess] BFD WGLC for draft-ietf-bfd-vxlan; BESS input solicited

Hi Anoop,
thank you for your comments and the suggested text. To clarify the extent
of the update, would the following accurately reflect the change in
Introduction you're proposing:
OLD TEXT:
   VXLAN is typically deployed in data centers interconnecting
   virtualized hosts 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
   [RFC7348], by providing Layer 2 overlay scheme on a Layer 3 network.
NEW TEXT:
  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.

If my understanding of the proposed update is correct, I'd be glad to use
it (adding RFC 8365 as Informational reference).  Should note that in the
draft we never used "End Station". Perhaps the last sentence is not
required.

What do you think?

Regards,
Greg
