Reviewer: Linda Dunbar Review result: Ready 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 of the review is Ready with comment The described mechanism for LSP Multipath Ping is very clear. The Security Consideration re-uses the description of RFC8029, which is very comprehensive. It would be better if the draft describes how to prevent intermediate LSRs in between the Initiating LSR and Responding LSR from mis-using the detailed link information (e.g. forwarding to somewhere else). Best Regards, Linda Dunbar
