# Éric Vyncke, INT AD, comments for draft-ietf-idr-bgp-car-15
CC @evyncke

Thank you for the work put into this document. Due to time constraints, I have
only browsed this document, sorry about this light review.

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

Special thanks to Sue Hares for the shepherd's very detailed write-up including
the WG consensus *and* the justification of the intended status, it is also
quite old, i.e., I wonder whether things have changed since April 2024.

I hope that this review helps to improve the document,

Regards,

-éric

## COMMENTS (non-blocking)

### Section 1

The letter "E" is used, but I failed to see its definition. Same for "E2" in
section 1.1. Even saying 'E' = edge would help.
DR# Added an Abbreviation entry for ‘E’.

### Section 1.1

Unsure how to read `Where the network uses SRv6, the operators have agreed to
trust each other's specification of SRv6 SIDs.` In the case of multiple
operators, I would assume that *all* transport (bein plain IP or SR MPLS or
SRv6) relies on a trust relationship. Unsure what is a specification of SRv6
SIDs, suggest using "allocation" ?
DR# Have edited this statement; please check.

### Section 2.5

Should a reference be added for SRv6 Flex Algo ? Same later for "TEA".
DR# They are referenced earlier in Terminology and Abbreviations.

### Section 2.9.2.1 (and possible other places)

Even if somehow obvious, please state the unit for the Length field.
DR# Added.

### Section 2.9.2.3

s/a stack of 128-bit SRv6 SIDs/an ordered list of 128-bit SRv6 SIDs/ ? SRH is
not about 'stack' of labels.
DR# Fixed.

## NITS (non-blocking / cosmetic)

### Use of SVG graphics

To make a much nicer HTML rendering, suggest using the aasvg too to generate
SVG graphics. It is worth a try ;-)
DR# Couldn’t spend time on this.
