Well, I personally don't read the text in RFC 6437 as saying "a violation to the rule can be accepted for compelling reasons". To avoid arguments with difficult individuals like me, you might take a more neutral approach: This document updates the following text from RFC 6437, "IPv6 Flow Label Specification": OLD: Once set to a non-zero value, the Flow Label is expected to be delivered unchanged to the destination node(s). A forwarding node MUST either leave a non-zero flow label value unchanged or change it only for compelling operational security reasons as described in Section 6.1. NEW: Once set to a non-zero value, the Flow Label is expected to be delivered unchanged to the destination node(s). A forwarding node MUST either leave a non-zero flow label value unchanged or change it only for (1) compelling operational security reasons as described in Section 6.1 or (2) use as specified in RFC-to-be, "The IPv6 Flow Label within a RPL domain". - Ralph > > What do you think? > > Cheers, > > Pascal > > >> -----Original Message----- >> From: Philip Levis [mailto:pal@cs.stanford.edu] >> Sent: lundi 4 août 2014 20:23 >> To: Ralph Droms >> Cc: Pascal Thubert (pthubert); Michael Richardson; Routing Over Low power >> and Lossy networks; ipv6@ietf.org >> Subject: Re: [Roll] WGLC for draft-thubert-6man-flow-label-for-rpl-03 >> >> >> On Aug 4, 2014, at 11:10 AM, Ralph Droms <rdroms.ietf@gmail.com> wrote: >> >>> >>> On Aug 4, 2014, at 2:01 PM 8/4/14, Pascal Thubert (pthubert) >> <pthubert@cisco.com> wrote: >>> >>>> The change is now done, Ralph. >>>> >>>> The only difference between draft-thubert-6man-flow-label-for-rpl-03 and >> draft-thubert-6man-flow-label-for-rpl-04 is >>>> >>>> Updates: 6437 (if approved) >>> >>> I suggest adding a section to your doc that explains exactly what is being >> updated in RFC 6437. >>> >>> - Ralph >> >> >> I agree.
