Hi, Acee:
The Sub-TLV described in Section 8 and section 9 of the draft-ietf-lsr-flex-algo is for Prefix Metric, not for Link Metric. Such sub-TLV is carried with the prefix advertisement. Will you change the name and application scope of such Sub-TLV? Currently, the name is “IS-IS Flexible Algorithm Prefix Metric Sub-TLV”, its application scope is limited in: “The IS-IS FAPM Sub-TLV is a sub-TLV of TLVs 135, 235, 236, and 237”. Same situation as OSPF Best Regards Aijun Wang China Telecom From: lsr-boun...@ietf.org <lsr-boun...@ietf.org> On Behalf Of Acee Lindem (acee) Sent: Wednesday, March 23, 2022 2:02 AM To: draft-lin-lsr-flex-algo-met...@ietf.org Cc: lsr@ietf.org Subject: [Lsr] Question on "Advertisement of Dedicated Metric for Flexible Algorithm in IGP" Speaking as WG member: Hi Co-authors, I’m read this draft and I really don’t see why you couldn’t just use the algorithm-specific metric in section 8 and 9 and draft-ietf-lsir-flex-algo? It seems to me that the use case is fairly obscure and there is nothing to prevent usage of these metrics for this use case and the draft is simply a matter of semantics. Thanks, Acee
