The Locator/ID Separation Protocol
RFC 9300, “The Locator/ID Separation Protocol”, is a Proposed Standard document published in October 2022 by D. Farinacci, V. Fuller, D. Meyer, D. Lewis, A. Cabellos. It obsoletes RFC 6830. The canonical text is published by the RFC Editor.
Abstract
This document describes the data plane protocol for the Locator/ID Separation Protocol (LISP). LISP defines two namespaces: Endpoint Identifiers (EIDs), which identify end hosts; and Routing Locators (RLOCs), which identify network attachment points. With this, LISP effectively separates control from data and allows routers to create overlay networks. LISP-capable routers exchange encapsulated packets according to EID-to-RLOC mappings stored in a local Map-Cache.
LISP requires no change to either host protocol stacks or underlay routers and offers Traffic Engineering (TE), multihoming, and mobility, among other features.
This document obsoletes RFC 6830.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
