Document: draft-ietf-6man-mtu-option-12 Reviewer: Sheng Jiang Review Date: 2022-02-09 This experimental document specifies a new mechanims to in-boundly discover the minimum Path MTU along the forward path between a source host to a destination host with a newly defined IPv6 Hop-by-Hop option that is used to record . The document is well-writen and reader-friendly. It clearly defines the behaviours on each devices with different roles. This document also have a special section 9 to explain the "experiment goals" of this specification. However, personally, I still not fully understand why this document are intending for "experimental" and what would be the experiment range. It seems for me this mechanism are good enough to be a proposed standard to persuade people use it widely. If by deploying it, issues are found or refining are needed. We can always update it as normal IETF procedure. Summary: Ready Major Concerns: None. Minor Concerns: None.
