Locator/ID Separation Protocol (LISP) Control-Plane
draft-ietf-lisp-rfc6833bis-23
Abstract
This document describes the Control-Plane and 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 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, which 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, their implementation and operational complexity
reduces the overall cost and effort of deploying LISP.
This document obsoletes RFC 6830 and 6833.
