Please find below one blocking DISCUSS points (easy to address), some non-blocking COMMENT points (but replies would be appreciated even if only for my own education), and some nits. Special thanks to Acee Lindem for the shepherd's detailed write-up including the WG consensus *and* the justification of the intended status, there is no justification for six authors though. I hope that this review helps to improve the document, Regards, -éric ## COMMENTS (non-blocking) ### Support of metrics by IGP routers It is perhaps specified in other RFCs, but I failed to see the specification of what to do when a router receives a metric that it does not support. <SH> All the new metrics are used by Flex-algo. If a flex-algo definition (FAD)includes a metric-type that is not supported/understood by a router, it stops participating in that flex-algo. This behavior is specified in RFC 9350 And this document need not repeat this statement IMO . The router would simply flood the LSPs/LSAs Even if it did not understand the metric. This behaviour is defined in base OSPF/ISIS standards ### Section 1 Should the terms throughput be used in addition to bandwidth ? E.g., s/High bandwidth traffic/High throughput traffic/ ? <SH>I searched the RFCs a bit and couldn't find other RFCs using the term high bandwidth traffic, I also couldn't find the term high throughput traffic . But for now I am changing it to "high throughput traffic". s/This document proposes /This document specifies / (or "defines"), after all it will be published as a PS RFC ;-) <SH> ok Else, this section is super well written and easy to read. Suggest adding a reference to "PCE". <SH>OK ### Section 2 Suggest adding references to IS-IS and OSPF. <SH>ok Please expand "ASLA". <SH> ok ### Section 2.1 It took me a while to understand that figure 1 is not part of bullet item g. Please insert some leading text to ensure a clear understanding of the figure 1 between bullet g and the figure 1. Like done in section 2.2 for figure 2. <SH> ok ### Sections 2.1 & 2.2 `The value is taken from the "IGP metric-type" registry maintained by IANA`, but it was written previously that values 128-255 are for private use. <sH> yes. The value can be 0-127 or user defined 128-255. All these are defined in the "IGP metric-type" registry maintained by IANA. Pls refer IANA section ### Section 3.1.1 Should there be a reference to `IEEE floating point format (32 bits)` ? <SH> RFC 5305 uses this but I couldn't find a reference. Its well known, I would believe. ### Section 10.1 Strongly suggest to add a reference to https://urldefense.com/v3/__https://www.iana.org/assignments/igp-parameters/igp-parameters.xhtml*igp-metric-type__;Iw!!NEt6yMaO-gk!C91vbUitzDkF8V1c0kH31BLKVBdwYOTMEXaU1XYgFXBCxXmBC4Eq_XizG2w2n0GSs9uICRCd_lM2amfO$ rather than using "IGP Metric-type Registry" <SH>ok. I am still figuring how to add reference , will do in later version ## NITS (non-blocking / cosmetic) ## Requirements language While correct, it appears at an unusual location. I guess that the RFC editor will fix it. <SH> ok ### Section 2.1 s/0XFFFFFF/0xFFFFFF/ or be consistent on how to write hexadecimal constant. <SH> OK ### Section 9 s/When user defined metrics/When user-defined metrics/ <SH> OK ### Section 10.1 s/ pariticular / particular / <SH> OK ### Use of SVG graphics To make a much nicer HTML rendering, suggest using the aasvg too to generate SVG graphics. It is worth a try ;-) _______________________________________________ Lsr mailing list -- lsr@ietf.org To unsubscribe send an email to lsr-le...@ietf.org
