A new Request for Comments is now available in online RFC libraries. RFC 9302 Title: Locator/ID Separation Protocol (LISP) Map-Versioning Author: L. Iannone, D. Saucez, O. Bonaventure Status: Standards Track Stream: IETF Date: October 2022 Mailbox: luigi.iannone@huawei.com, damien.saucez@inria.fr, Olivier.Bonaventure@uclouvain.be Pages: 15 Obsoletes: RFC 6834 I-D Tag: draft-ietf-lisp-6834bis-14.txt URL: https://www.rfc-editor.org/info/rfc9302 DOI: 10.17487/RFC9302 This document describes the Locator/ID Separation Protocol (LISP) Map-Versioning mechanism, which provides in-packet information about Endpoint-ID-to-Routing-Locator (EID-to-RLOC) mappings used to encapsulate LISP data packets. This approach is based on associating a version number to EID-to-RLOC mappings and transporting such a version number in the LISP-specific header of LISP-encapsulated packets. LISP Map-Versioning is particularly useful to inform communicating Ingress Tunnel Routers (ITRs) and Egress Tunnel Routers (ETRs) about modifications of the mappings used to encapsulate packets. The mechanism is optional and transparent to implementations not supporting this feature, since in the LISP-specific header and in the Map Records, bits used for Map-Versioning can be safely ignored by ITRs and ETRs that do not support or do not want to use the mechanism. This document obsoletes RFC 6834, which is the initial experimental specifications of the mechanisms updated by this document. This document is a product of the Locator/ID Separation Protocol 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.
