A new Request for Comments is now available in online RFC libraries. RFC 8920 Title: OSPF Application-Specific Link Attributes Author: P. Psenak, Ed., L. Ginsberg, W. Henderickx, J. Tantsura, J. Drake Status: Standards Track Stream: IETF Date: October 2020 Mailbox: ppsenak@cisco.com, ginsberg@cisco.com, wim.henderickx@nokia.com, jefftant.ietf@gmail.com, jdrake@juniper.net Pages: 19 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ospf-te-link-attr-reuse-16.txt URL: https://www.rfc-editor.org/info/rfc8920 DOI: 10.17487/RFC8920 Existing traffic-engineering-related link attribute advertisements have been defined and are used in RSVP-TE deployments. Since the original RSVP-TE use case was defined, additional applications (e.g., Segment Routing Policy and Loop-Free Alternates) that also make use of the link attribute advertisements have been defined. In cases where multiple applications wish to make use of these link attributes, the current advertisements do not support application-specific values for a given attribute, nor do they support indication of which applications are using the advertised value for a given link. This document introduces new link attribute advertisements in OSPFv2 and OSPFv3 that address both of these shortcomings. This document is a product of the Link State Routing Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
