A new version of draft-ietf-6lowpan-nd is now available at:
http://www.ietf.org/internet-drafts/draft-ietf-6lowpan-nd-03.txt
We've worked hard to close most of the tickets on this draft, and it it
now leaner and much more complete. Thanks to everyone for the hard work
on discussion and comments.
Changes:
- Updated terminology, with RFC4861 non-transitive link model
- 6LoWPAN and ND terminology separated
- Protocol overview explains RFC4861 diff in detail
- RR/RC is now Node Registration/Confirmation (NR/NC)
- Added NR failure codes
- ER Metric now included in 6LoWPAN Prefix Summary option for use in
default router determination by hosts
- Examples of host data structures, and the Whiteboard given
- Whiteboard is supported by all Edge Routers for option simplicity
- Edge Router Specification chapter re-structured, clarifying optional
Extended LoWPAN operation
- NS/NA now completely optional for nodes. No address resolution or
NS/NA NUD required.
- Link-local operation now compatible with oDAD (was broken)
- Exception to hop limit = 255 for NR/NC messages
- Security considerations improved
- ICMPv6 destination unreachable supported
Before the Stockholm cutoff we will submit -04 of the draft. Now it is
time for full reviews, security reviews and implementor feedback within
the next 3-4 weeks. We will be fishing for AD and IAB feedback as well
before Stockholm.

Filename: draft-ietf-6lowpan-nd
Revision: 03
Title: Neighbor Discovery for 6LoWPAN
Creation_date: 2009-05-28
WG ID: 6lowpan
Number_of_pages: 52
Abstract:
This document specifies Neighbor Discovery optimized for 6LoWPAN.
The 6LoWPAN format allows IPv6 to be used over energy and bandwidth
constrained wireless networks often making use of multihop
topologies. However, the use of standard IPv6 Neighbor Discovery
with 6LoWPAN has several problems. Standard Neighbor Discovery was
not designed for non-transitive wireless links, and the standard IPv6
link concept and heavy use of multicast makes it inefficient. This
document specifies a new ND mechanism allowing for the efficient
detection of duplicate addresses over entire LoWPANs while avoiding
or simplifying other ND operations. In addition it specifies context
dissemination for use with router advertisements, claim and defend
address generation, and the support of Extended LoWPANs over backbone
links.
