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.
