The IESG has received a request from the Routing Over Low power and Lossy
networks WG (roll) to consider the following document: - 'RNFD: Fast border
router crash detection in RPL'
  <draft-ietf-roll-rnfd-05.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2025-02-17. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   By and large, a correct operation of a RPL network requires border
   routers to be up.  In many applications, it is beneficial for the
   nodes to detect a crash of a border router as soon as possible to
   trigger fallback actions.  This document describes RNFD, an extension
   to RPL that expedites border router failure detection, even by an
   order of magnitude, by having nodes collaboratively monitor the
   status of a given border router.  The extension introduces an
   additional state at each node, a new type of RPL Control Message
   Options for synchronizing this state among different nodes, and the
   coordination algorithm itself.
