Document: draft-ietf-detnet-mpls-over-ip-preof-08 Reviewer: Joel Halpern Review Date: 2023-12-19 IETF LC End Date: 2023-12-22 IESG Telechat date: Not scheduled for a telechat Summary: This document is ready for publication as an Informational RFC Major issues: N/A Minor issues: N/A Nits/editorial comments: The term PREOF is used without any expansion or definition in the introduction. Some elaboration of the term should be included at first usage. It may make sense to define F-label even though all the references to it in this document are saying that it is not used. As a reader, I was left inferring what was not being done.
