Hi Aijun,

I have difficulty with the problem you are trying to solve, could you expand on 
that section a little ?

Other than that, shouldn’t this document go through NVO3 first, to define the 
dataplane aspects of extending VxLAN-GPE? Once dataplane is defined, it can 
(separately) move through BESS for signaling aspects.

The document doesn’t refer to draft-ietf-nvo3-vxlan-gpe - this should be a 
normative reference if you are extending vxlan-gpe.

Regards,
Luc André

Hi, All experts:

After several rounds offline discussions about the previous version of this 
document, with our Chair, Jeffery Zhang, we updated again the related 
descriptions, to reflect the converged conclusions.
We would like to seek more broader reviews of this document and get some 
constructive comments to forward it.
We have also applied one time slot on the coming IETF 122 meeting to make one 
presentation. If the time slot is granted, let's discuss it further on the 
meeting, or after the meeting.

Please take some time to review it 
https://datatracker.ietf.org/doc/html/draft-wang-bess-l3-accessible-evpn
If you are familiar with the layer 2 access interface(VLAN based, VLAN bundle, 
VLAN awared) of EVPN(RFC 7432), then it is easy to understand the aim and 
solution of this draft.

Thanks in advance for your efforts! And thank also Jeffrey Zhang for the 
discussions to improve the document.

Best Regards

Aijun Wang

Abstract:

   This draft describes layer-3 accessible EVPN service interfaces,
   which aim is to connect the layer 2 customers to one EVPN backbone,
   via the layer 3 network, and keep the traffic isolation among
   different layer 2 customers.  It proposes to extend the VxLAN packet
   format to transfer the customer's Virtual Network Identifier(VNI)
   information, and also the related control plane extension.
