Beno=EEt and Med,

 

Thanks for this document, pleas= e find below some comments on the IPv6 sections (4.1 and 9.1), obviously we= aring no hat. I like the idea of creating a registry mapping IPFIX IE bits = to IPv6 extension headers, even if there won=92t be any new IPv6 extension headers.

 

Another important issue is to e= xport whether the full extension header chain has been parsed as some HW ca= n only process so many headers or so many bytes. In this case, the bit mask= is obviously incomplete. This could of course be another bit in the mask and could be specified in the compani= on I-D, draft-ietf-opsawg-ipfix-tcpo-v6eh.

 

# Section 9.1

 

Should there be an entry to =93= no next header=94 value ?

 

Should there be different bits = for =93destination options=94 as this one can happen *before* and *<= b>after* routing header ? Similar to FRA0 and FRA1 bits ?

 

Please replace the =93IPv6 opti= ons=94 column by =93IP protocol number=94 or =93IPv6 Next-Header Values=94<= /span>

 

Use =93IPv6 Hop-by-Hop Options= =94 (plural) per RFC 8200 (even the IANA-EH registry is singular)

 

The first =93Note=94 already ap= pears a couple of lines above ;-)

 

 

Hope this helps
