Technical Summary

This specification updates RFC 6775 - 6LoWPAN Neighbor Discovery, to
clarify the role of the protocol as a registration technique,
simplify the registration operation in 6LoWPAN routers, as well as to
provide enhancements to the registration capabilities and mobility
detection for different network topologies.

Working Group Summary

There has been plenty of discussion about these extensions in the working group. This document started in Oct. 2016 as an individual submission, but ideas were discussed even previous to that, including a requirements document (draft-thubert-6lo-rfc6775-update-reqs) which fed into this document, 6775bis. There have been 10 revisions based on implementation experience. Initially, it was a controversial document since it affects how IPv6 ND works in certain networks. This prompted some concern from IPv6 folks (e.g., Lorenzo Colitti) concerned that these modifications were not generally applicable to all link layers or situations. In response, the authors made changes to clarify the scope of the extensions. Section 2, in particular was modified as a result of these debates and exchanges.

Document Quality

These extensions have been implemented in open source (OpenWSN, Cisco IOS) and have been tested in 6TiSCH/6lo ETSI Plugtest.

Personnel

Gabriel Montenegro is the Document Shepherd. Suresh Krishnan is the Responsible Area Director.
