    abstract =  {This document specifies a point-to-point route discovery mechanism, complementary to the RPL core functionality. This mechanism allows an IPv6 router to discover and establish, on demand, a route to another IPv6 router in the LLN such that the discovered route meets specified metrics constraints, without necessarily going along the DAG links established by core RPL.},
