1. Introduction
This document describes how the Locator/Identifier Separation
Protocol (LISP) can obtain, measure, and distribute data-plane
telemetry information. LISP is an encapsulation protocol built
around the fundamental idea of separating the topological location of
a network attachment point from the node's identity
[I-D.ietf-lisp-rfc6830bis]. As a result LISP creates two namespaces:
Endpoint Identifiers (EIDs), that are used to identify end-hosts and
routable Routing Locators (RLOCs), used to identify network
attachment points. LISP then defines functions for mapping between
the two namespaces and for encapsulating traffic originated by
devices using non-routable EIDs for transport across a network
infrastructure that routes and forwards using RLOCs.
This document specifies how a decapsulating xTR returns telemetry
data to an encapsulating xTR using RLOC-probe messages defined in
[I-D.ietf-lisp-rfc6833bis].
Early versions of this document will define the type and format of
the telemetry data and how it will be distributed. Later versions of
this document will describe how telemetry measurement will be
performed.
