Hi Emmanuel, I think if route over protocols are to adhere to RFC 5889, much more work needs to go into making ULAs useful.
For our project we used: 6LoWPAN (RFC 4944), 6LoWPAN-ND (RFC 6775), ROLL RPL (RFC 650), mDNS (RFC 6762) with some extensions to use ULAs (among others) and I can say that simply not using link locals with RFC 5889 would not yield a robust IoT solution (at least this is my opinion having worked on this for 4 years now) Don From: Emmanuel Baccelli <emmanuel.bacce...@inria.fr> Date: Friday, July 26, 2013 1:50 AM To: Routing Over Low power and Lossy networks <r...@ietf.org> Cc: "6...@ietf.org" <6...@ietf.org> Subject: Re: [Roll] Dissenting technical arguments unwelcome Hi Michael, actually, MANET protocols have been working for years to provide mesh-over routing, without multi-link subnets. To understand better the "link" properties you have to deal with, you could take a look at this draft http://tools.ietf.org/html/draft-baccelli-manet-multihop-communication-02 As Ulrich mentioned, the conclusion of AUTOCONF was that IP links as we know them do *not* make sense in a spontaneous wireless multi-hop environment. This conclusion was documented in RFC 5889, which essentially bans the use of subnet prefixes in this environment. And without subnet prefixes, what is the purpose of an IP link? Not much...
