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.
