Hello,

ROLL WG kindly request for a routing directorate review and security directorate review of draft-ietf-roll-dao-projection-31. 

The review deadline is 22 of January. If you need more time please let us know.

Abstract: "This document extends RFC 6550, RFC 6553, and RFC 8138 to enable a RPL Root to install and maintain Projected Routes within its DODAG, along a selected set of nodes that may or may not include itself, for a chosen duration.  This potentially enables routes that are more optimized or resilient than those obtained with the classical distributed operation of RPL, either in terms of the size of a Routing Header or in terms of path length, which impacts both the latency and the packet delivery ratio."

Many thanks,

Ines.

Hi,

I believe the authors adequately described the different attack vectors when
P-DAOs are introduced. The mitigating measures like requiring that only the
root can send P-DAO and validation of VIO seem reasonable.
