# Éric Vyncke, INT AD, comments for
draft-ietf-bess-mvpn-evpn-aggregation-label-11

Thank you for the work put into this document.

Please find below two blocking DISCUSS points (easy to address), some non-blocking COMMENT points (but replies would be appreciated even if only for my own education), and some nits.

Special thanks to Stéphane Litkowski for the shepherd's detailed write-up including the WG consensus ***but it lacks*** the justification of the intended status.

I hope that this review helps to improve the document,

Regards,

-éric

# DISCUSS

As noted in https://urldefense.com/v3/__https://www.ietf.org/blog/handling-iesg-ballot-positions/__;!!NEt6yMaO-gk!DjXuL1noCSa5WhUuS_bagMtl618K7y88Y_-qasDkUDNDfZ35V5l7ZaLNrjHA44aocSkdXbcTXkvFe6c$ , a DISCUSS ballot is a request to have a discussion on the following topics:

## Shepherd write-up

The shepherd write-up includes `Martin Vigoureux is the responsible AD`.

The shepherd write-up includes `There is one IPR`, while data tracker has 2 IPR declarations. At least, the auto-generated IETF Last Call correctly listed the two IPR declarations.

The above parts are obviously outdated and MUST be updated.

This is not really a DISCUSS criteria, so I will change my ballot after the IESG formal telechat or after an update of the shepherd write-up (the earlier).

## Wrong reference to RFC5531

As indicated by idnits, there is a reference to RFC 5531 (it should probably be RFC 5331)

# COMMENTS

## Abstract

Should the abstract qualify the VPN with layer-3 (for MVPN) and layer-2 (for
EVPN) ?

## Section 1

Should "SR" also be expanded ? Should RFC 8660 be a reference ?

## Section 2

`to transmit multicast traffic or BUM traffic` is somehow redundant as BUM includes multicast.

## Section 2.1

`At the present time` what about "In 2023, " ?

## Section 3.1

Please expand "EC" at first use (even if it can be guessed on the previous sentence).

Why this section use `to be defined by IANA`, while section 5 lists the IANA-assigned values ?

## Section 3.2

This I-D uses 'outside the scope of this document' twice. I am curious: is there any work in BESS WG for this ?
