Dear authors I reviewed the changes (only) and have some queries and suggestions for the PDR and Sibling Information Option - P-DAO Request Message - [Suggestion] When a LN/LR requests for TE path using PDR it can mention the Network Metric that PCE need to consider while computing the P-Route. Like A node can request for a TE path based of Hop Count or based on Minimum latency or Minimum EXT or Maximum Battery Life. I think this will provide more flexibility for application. - [Query] Can PCE be a separate Physical Node Other than BR? If Yes how LR/LN will learn about it and send the PDR to it? - Sibling Information Option (SIO) - [Query] If PCE is a separate physical entity how the Sibling informations will be shared with it, as DAO messages will always terminate at BR? - [Query] If the metric of P-Route need to be different from the Network Metric used for the global mesh network, how a LN/LR is going to learn about that so that it can send the correct metric information in SIO? - [Issue] Description of Sibling Address filed of SIO is exact copy of VIA address filed in VIO (2 to 16 bytes, a compressed IPv6 Address. a *Via Address indicates* the next hop towards the destination(s).....). This need to be changed.
