IETF RFC 9301 PDF

This document describes the control plane and Mapping Service for the Locator/ID Separation Protocol (LISP), implemented by two types of LISP-speaking devices -- the LISP Map-Resolver and LISP Map-Server -- that provide a simplified "front end" for one or more Endpoint IDs (EIDs) to Routing Locator mapping databases.

By using this control plane service interface and communicating with Map-Resolvers and Map- Servers, LISP Ingress Tunnel Routers (ITRs) and Egress Tunnel Routers (ETRs) are not dependent on the details of mapping database systems; this behavior facilitates modularity with different database designs. Since these devices implement the "edge" of the LISP control plane infrastructure, connecting EID addressable nodes of a LISP site, the implementation and operational complexity of the overall cost and effort of deploying LISP is reduced.

This document obsoletes RFCs 6830 and 6833.
