Point-to-point (P2P) communication between arbitrary routers in a Low-power and Lossy Network (LLN) is a key requirement for many home and commercial building automation applications [RFC5826] [RFC5867]. The IPv6 Routing Protocol for LLNs (RPL) [RFC6550] constrains the LLN topology to a Directed Acyclic Graph (DAG) built to optimize the routing costs to reach the DAG's root. The P2P routing functionality, available under RPL, has the following key limitations:

 A Mechanism to Measure the Routing Metrics along a Point-to-Point Route                     in a Low-Power and Lossy Network


   This document specifies a mechanism that enables a Routing Protocol    for Low-power and Lossy Networks (RPL) router to measure the    aggregated values of given routing metrics along an existing route    towards another RPL router, thereby allowing the router to decide if    it wants to initiate the discovery of a better route.
