Internet Engineering Task Force (IETF) P. Thubert, Ed. Request for Comments: 8505 Cisco Updates: 6775 E. Nordmark Category: Standards Track Zededa ISSN: 2070-1721 S. Chakrabarti Verizon C. Perkins Futurewei November 2018 Registration Extensions for IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) Neighbor Discovery Abstract This specification updates RFC 6775 -- the Low-Power Wireless Personal Area Network (6LoWPAN) Neighbor Discovery specification -- to clarify the role of the protocol as a registration technique and simplify the registration operation in 6LoWPAN routers, as well as to provide enhancements to the registration capabilities and mobility detection for different network topologies, including the Routing Registrars performing routing for host routes and/or proxy Neighbor Discovery in a low-power network.
