Abstract

   This specification updates 6LoWPAN Neighbor Discovery (RFC6775), to
   clarify the role of the protocol as a registration technique,
   simplify the registration operation in 6LoWPAN routers, and provide
   enhancements to the registration capabilities, in particular for the
   registration to a backbone router for proxy ND operations.
