The IESG has approved the following document: - 'IGP Flexible Algorithm' (draft-ietf-lsr-flex-algo-25.txt) as Proposed Standard
This document is the product of the Link State Routing Working Group. The IESG contact persons are Alvaro Retana, Andrew Alston and John Scudder. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-lsr-flex-algo/ Technical Summary: This document provides extensions to OSPF and IS-IS to use different algorithms to compute the paths to different prefixes. Since not all nodes in the computation domain (i.e., an OSPF or IS-IS area) may support every algorithm, SR or SRv6 is used to between nodes. Working Group Summary: The was good collaboration on the document. The only controversy came at the tail end of the process when there was some discussion as to whether RFC 8919 /RFC 8920 Application Specific Link Attributes (ASLAs) should be used for alternate metrics or whether the advetisements used for RSVP TE could also be used. The consensus was to allow RFC 8919/RFC 8920 attributes to be required. Discussion and implementation uncovered that some additional OSPF encodings were needed for ASBR routes. This resulted in updates and second WG Last Call. During the second WG Last Call, the discussion of the application specific attributes resulted in Errata to both RFC 8919 and 8920: https://www.rfc-editor.org/errata/eid6631 https://www.rfc-editor.org/errata/eid6630 Document Quality: The document is of high quality with vendors and operators reviewing. There are existing implementations of the document and three other WG documents that augment the base document: https://datatracker.ietf.org/doc/draft-ietf-lsr-ip-flexalgo/ https://datatracker.ietf.org/doc/draft-ietf-lsr-flex-algo-bw-con/ https://datatracker.ietf.org/doc/draft-ietf-lsr-algorithm-related-adjacency-sid/ Personnel: Document Shepherd: Acee Lindem Responsible AD: John Scudder _______________________________________________ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr
