Root initiated routing state in RPL
draft-ietf-roll-dao-projection-06
Abstract
This document extends RFC 6550, RFC 6553 and RFC 8138 and enable to
install a limited amount of centrally-computed routes in a RPL graph,
enabling loose source routing down a non-storing mode DODAG, or
transversal routes inside the DODAG. In constrast with classical
routes in RPL that are injected by the end devices, this draft
enables the root of the DODAG to projects the routes that are needed
on the nodes where they should be installed.
