As Brian says, we can't change the normative effect in the context of promoting the document to full standard. As for making room for exceptions: isn't it a given that any standards track document can update RFC 4291? (Assuming 6man has either reviewed and gotten consensus on it, or not requested to review it) On Fri, Jan 20, 2017 at 2:25 PM, David Farmer <farmer@umn.edu> wrote: > > > On Thu, Jan 19, 2017 at 10:38 PM, Lorenzo Colitti <lorenzo@google.com> > wrote: > >> On Fri, Jan 20, 2017 at 4:41 AM, Brian E Carpenter < >> brian.e.carpenter@gmail.com> wrote: >> >>> However, correct use of Stateless Address Autoconfiguration >>> (SLAAC)[RFC4862] requires all interfaces on a link to use the same >>> length >>> of Interface ID.
