Technical Summary
In Low power and Lossy Networks (LLNs), memory constraints on
routers may limit them to maintaining at most a few routes. In
some configurations, it is necessary to use these memory
constrained routers to deliver datagrams to nodes within the LLN.
The Routing for Low Power and Lossy Networks (RPL) protocol can
be used in some deployments to store most, if not all, routes on
one (e.g. the Directed Acyclic Graph (DAG) root) or few routers
and forward the IPv6 datagram using a source routing technique
to avoid large routing tables on memory constrained routers.
This document specifies a new IPv6 Routing header type for
delivering datagrams within a RPL domain.
Working Group Summary

represents the consensus of those groups.
Document Quality
Several external groups have indicated their plans to
carry out large-scale deployments using the RPL option
defined in this document.

Header", and hass been assigned assigned number TBD by IANA.
