Subject: Re: [bess] WGLC, IPR and implementation poll for draft-ietf-bess-evpn-virtual-eth-segment

Thanks a lot Ali for the updating.
Looks fine for me apart from one point.
Correct me if I am wrong for what mentioned below.
This document aims to enable capability of evpn to be used on ENNI. But ENNI also have EVPL, ELAN and ETREE services.  This document have a brilliant solution, but overall current document only mentions usage in ELAN, so the question is how about ETREE and VPWS? As the solution in this document is vES based, I believe it should work for ETREE and VPWS without much extra considerations.  So if authors agree, I prefer to cover this in the current document. It is also fine for me if authors' choice is out of scope and prefer to cover other scenarios in a separate document.

I have already added VPWS. However, there is no point to list every EVPN solution in this document or else we have to list not just evpn-etree but evpn-overlay, evpn-irb, evpn-mcast, evpn-fxc, etc.

By the way another nits..
Sub type in figure 6 is not consistent with description above. I got lost on this as previous version was still 0x04.. so if 0x07 is the correct one please fix the value in the figure

That has already been corrected.

Cheers,
Ali

Thanks a lot.

Regards,
Tim

Hi,

Support this work as an individual. This document is a great and elegant step for EVPN towards SP network.

Some small comments by the way:

1. Figure 2 shows the scope of EVPN network but the other figures in the document not. Please kindly update, then it is more readable.

2. There are 2 Figure 2

3. Document is lack of mention on E-Tree, it should work without any extra consideration right?

4. Please fix format issue in section 8 and update TBD in section 9.

Thanks,

Tim
