Re: [Roll] WGLC for draft-thubert-6man-flow-label-for-rpl-03

[Philip Levis <[e-mail]>]

Seems reasonable to me, although a bit cumbersome. I'd suggest

  This document updates the IPv6
  Flow Label Specification [RFC6437], which stipulates that once the Flow
  Label is set, forwarding nodes do not update it unless there are compelling
  security reasons to do so. This document argues that saving energy in LLNs 
  is another sufficiently compelling reason to modify the Flow Label.
