Benoit Claise has entered the following ballot position for draft-ietf-rtgwg-rlfa-node-protection-10: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-rtgwg-rlfa-node-protection/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- This document mentions manageability in his title. Hence my special focus. I'm with Eric Vyncke here. His OPS DIR review is: Not being an expert in LFA, the review focus was only on operation. And, due to the density and specialization of the I-D, I would like to ask the authors whether they read RFC 5706 about 'ops and mgmt guidelines', i.e., to check whether this I-D considered migration from an existing LFA to the new one, interoperations with previous LFA and how correct operations can be verified. As the core topic is about loop-free alternates, we can assume that fault management and operations are at the core of this I-D. But, I encourage the authors to quickly review their document with RFC 5706 in mind. After reading the document (and with basic knowledge of RLFA), I'm unable to tell at this point if RFC 7916 is still valid for this new functionality, if it needs to be updated, or even if https://tools.ietf.org/html/draft-ietf-rtgwg-rlfa-node-protection-10#section-3 is complete in light of RFC 5706. I'll be watching the discussion with interest. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- - The resulting Remote-LFA alternate nexthops (also referred to as the PQ-nodes) may not provide node-protection for all destinations covered by the same, in case of failure of the primary nexthop node. Covered by the same? - There are also some nits and typos such as " uitilized" in the abstract.
