Dear all : As you may know, draft-ietf-roll-unaware-leaves is blocking the whole cluster C130 https://www.rfc-editor.org/cluster_info.php?cid=C310 and we want to ship it now (WG milestone: Mar 2020 - Initial submission). The issue we have with it is the fact that we allow encapsulate the ARO status in a RPL status and we need bits to signal that.
To free the necessary bits the proposal on the table is to reduce the possible values for the ARO status to 0-63. This can be done by a simple IANA action that can be taken from draft-ietf-roll-unaware-leaves but we wanted to ensure that both ROLL and 6lo agree with the proposal: 12.1. Resizing the ARO Status values IANA is requested to modify the Address Registration Option Status Values Registry as follows: The unassigned values range is reduced from 11-255 to 11-63. NB: this will free 2 bits in the Extended Address Registration Option and the Extended Duplicate Address Message, could become handy in the future. Is there an issue with this that we are missing? Pascal
