Abstract

   There are a number of critical circumstances where a localized
   routing domain needs to augment or modify its view of the Global
   RPKI.  This document attempts to outline a few of them.

1.  Introduction

   Today RPKI-based Origin Validation, [RFC6811], relies on widespread
   deployment of the Global Resource Public Key Infrastructure (RPKI),
   [RFC6480].  In the future, RPKI-based Path Validation,
   [I-D.ietf-sidr-bgpsec-overview], will be even more reliant on the
   Global RPKI.

   But there are critical circumstances in which a local, clearly-
   scoped, administrative and/or routing domain will want to augment
   and/or modify their internal view of the Global RPKI.

   This document attempts to lay out a few of those use cases.  It is
   not intended to be authoritative, complete, or to become a standard.
   It merely tries to lay out a few critical examples to help frame the
   issues.

2.  Suggested Reading

   It is assumed that the reader understands the RPKI, see [RFC6480],
   the RPKI Repository Structure, see [RFC6481], Route Origin
   Authorizations (ROAs), see [RFC6482], and GhostBusters Records, see
   [RFC6493].

3.  What is 'Local'

   The RPKI is a distributed database containing certificates, CRLs,
   manifests, ROAs, and GhostBusters Records as described in [RFC6481].
   Policies and considerations for RPKI object generation and
   maintenance are discussed elsewhere.

   Like the DNS, the Global RPKI tries to present a single global view,
   although only a loosely consistent view, depending on timing,

   updating, fetching, etc.  There is no 'fix' for this, it is not
   broken, it is the nature of distributed data with distributed caches.

   There are critical uses of the RPKI where a local administrative and/
   or routing domain, e.g. an end-user site, a particular ISP or content
   provider, an organization, a geo-political region, ... may wish to
   have a specialized view of the RPKI.

   For the purposes of this exploration, we refer to this localized view
