Abstract

This document describes the Locator/ID Separation Protocol (LISP)Map-Versioning mechanism, which provides in-packet information aboutEndpoint-ID-to-Routing-Locator (EID-to-RLOC) mappings used toencapsulate LISP data packets. This approach is based on associatinga version number to EID-to-RLOC mappings and transporting such aversion number in the LISP-specific header of LISP-encapsulatedpackets. LISP Map-Versioning is particularly useful to informcommunicating Ingress Tunnel Routers (ITRs) and Egress Tunnel Routers(ETRs) about modifications of the mappings used to encapsulatepackets. The mechanism is optional and transparent toimplementations not supporting this feature, since in theLISP-specific header and in the Map Records, bits used forMap-Versioning can be safely ignored by ITRs and ETRs that do notsupport or do not want to use the mechanism.

This document obsoletes RFC 6834, which is the initial experimentalspecifications of the mechanisms updated by this document.
