This document presents a method to safely elide a group of RPL options in a DIO message by synchronizing the state associated with each of these options between parent and child using a new sequence counter in DIO messages. A child that missed a DIO message with an update of any of those protected options detects it by the change of sequence counter and queries the update with a DIS Message. The draft also provides a method to fully elide the options in a DAO message.
