I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The summary is READY This document defines a new DLEP Extension Type and three new DLEP Data Items to allow modems which implement multi-hop forwarding to change multi-hop forwarding behavior through a new hop-control mechanism defined by these extensions. The Security Considerations section was updated to explicitly note this addition of a hop-control mechanism which can be used to terminate and reset connections, affecting reacheability. As this new extension is defined under the existing RFC 8175 framework, the Security Considerations stated there also apply.
