   Locator/ID Separation Protocol Delegated Database Tree (LISP-DDT)
                     Referral Internet Groper (RIG)

Abstract

   A simple tool called the Locator/ID Separation Protocol Delegated
   Database Tree (LISP-DDT) Referral Internet Groper (RIG), also
   referred to in this document as "rig", can be used to query the LISP-
   DDT hierarchy.  This document describes how the "rig" tool works.

1.  Introduction

   "The Locator/ID Separation Protocol (LISP)" [RFC6830] specifies an
   architecture and mechanism for replacing the semantics of an address
   currently used by IP with two separate namespaces: Endpoint
   Identifiers (EIDs), used within sites; and Routing Locators (RLOCs),
   used on the transit networks that make up the Internet
   infrastructure.  To achieve this separation, LISP defines protocol
   mechanisms for mapping from EIDs to RLOCs.  In addition, LISP assumes
   the existence of a database to store and propagate those mappings
   globally.  This document focuses on the LISP Delegated Database Tree
   (LISP-DDT) [RFC8111] mapping database system.

   The "rig" tool is a manual management tool to query the LISP-DDT
   mapping database hierarchy.  It can be run by all devices that
   implement LISP, including Ingress Tunnel Routers (ITRs), Egress
   Tunnel Routers (ETRs), Proxy ITRs (PITRs), Proxy ETRs (PETRs),
   Map-Resolvers, Map-Servers, and LISP-DDT nodes, as well as by a host
   system at either a LISP-capable or non-LISP-capable site.

   The LISP-DDT "rig" tool is similar to the "LISP Internet Groper"
   ("lig") tool [RFC6835] in that they are both diagnostic tools to
   query a database.  However, the "rig" tool is used to find
   Map-Servers serving an EID-prefix, specifically within a LISP-DDT
   mapping database framework.  And "lig" can be used on top of any
   mapping database system to retrieve locators used for packet
