Internet Engineering Task Force (IETF) V. Fuller Request for Comments: 6833 Category: Experimental D. Farinacci ISSN: 2070-1721 Cisco Systems January 2013 Locator/ID Separation Protocol (LISP) Map-Server Interface Abstract This document describes the Mapping Service for the Locator/ID Separation Protocol (LISP), implemented by two new types of LISP- speaking devices -- the LISP Map-Resolver and LISP Map-Server -- that provides a simplified "front end" for one or more Endpoint ID to Routing Locator mapping databases. By using this service interface and communicating with Map-Resolvers and Map-Servers, LISP Ingress Tunnel Routers and Egress Tunnel Routers are not dependent on the details of mapping database systems, which facilitates experimentation with different database designs. Since these devices implement the "edge" of the LISP infrastructure, connect directly to LISP-capable Internet end sites, and comprise the bulk of LISP-speaking devices, reducing their implementation and operational complexity should also reduce the overall cost and effort of deploying LISP.

Introduction The Locator/ID Separation Protocol [RFC6830] specifies an architecture and mechanism for replacing the addresses currently used by IP with two separate name spaces: Endpoint IDs (EIDs), used within sites; and Routing Locators (RLOCs), used on the transit networks that make up the Internet infrastructure. To achieve this separation, LISP defines protocol mechanisms for mapping from EIDs to RLOCs. In addition, LISP assumes the existence of a database to store and propagate those mappings globally. Several such databases have been proposed; among them are the Content distribution Overlay Network Service for LISP (LISP-CONS) [LISP-CONS], LISP-NERD (a Not-so-novel EID-to-RLOC Database) [RFC6837], and LISP Alternative Logical Topology (LISP+ALT) [RFC6836].
