Cisco Cisco This document proposes a protocol extension to RPL that enables 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. As opposed to the classical route injection 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.
