Locator/ID Separation Protocol (LISP) Map-Versioning
Abstract
This document describes the LISP (Locator/ID Separation Protocol)
Map-Versioning mechanism, which provides in-packet information about
Endpoint ID to Routing Locator (EID-to-RLOC) mappings used to
encapsulate LISP data packets. The proposed approach is based on
associating a version number to EID-to-RLOC mappings and the
transport of 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 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 the
mechanism.
Status of This Memo
