Abstract

   There are circumstances in RPKI operations where a resource holder's
   parent may not be able to, or may not choose to, facilitate full and
   proper registration of the holder's data.  As in real life, the
   holder may form a relationship to their grandparent who is willing to
   aid the grandchild.  This document describes simple procedures for
   doing so.

1.  Introduction

   There are circumstances in RPKI operations where a resource holder's
   parent may not be able to, or may not choose to, facilitate full and
   proper registration of the holder's data.  As in real life, the
   holder may form a relationship to their grandparent who is willing to
   aid the grandchild.  This document describes simple procedures for
   doing so.

   One example would be when provider A allowed a child, C, to move to
   other provider(s) and keep their address space, either temporarily or
   permanently, and C's child, G, wished to stay with provider A.

   Other examples occur in administrative hierarchies, such as large
   organizations or military and other government hierarchies, when A's
   child C wishes to manage their own data but does not wish the
   technical or administrative burden of managing their children's, Gs',
   data.

2.  Suggested Reading

   It is assumed that the reader understands the RPKI, see [RFC6480],
   ROAs, see [RFC6482], BGPSEC Router Certificates, see
   [I-D.ietf-sidr-bgpsec-pki-profiles], and the operational guidance for
   origin validation, [I-D.ietf-sidr-origin-ops].

3.  What to Do

   A hypothetical example might be that A has the rights to 10.0.0.0/8,
   has delegated 10.42.0.0/16 to their child C, who delegated
   10.42.2.0/23 to their child G. C has changed providers and kept, with
   A's consent, 10.42.0.0/16, but G wishes to stay with A and keep
   10.42.2.0/23.

   Perhaps there are also AS resources involved, and G wishes to issue
   Router Certificates for their AS(s).

   Managing RPKI data in such relationships is simple, but should be
   done carefully.

   First, using whatever administrative and/or contractual procedures
   are appropriate in the local hierarchy, the grandparent, A, should
   ensure their relationship to the grandchild, G, and that G has the
   right to the resources which they wish to have registered.  These are
   local matters between A and G.

   Although A has the rights over their child's, C's, resources, it
   would be prudent and polite to ensure that C agrees to A forming a
   relationship to G. Again, these are local matters between A, C, and
   G.

   Then, it is trivial within the RPKI for A to certify G's data, even
   though it is a subset of the resources A delegated to C. A may
   certify G's resources, or issue one or more EE certificates and ROAs
   for G's resources.  Which is done is a local matter between A and G.

4.  Security Considerations

   This operational practice presents no technical security threats
   beyond those of the relevant RPKI specifications.

   There are threats of social engineering by G, lying to A about their
   relationship to and rights gained from C.

   There are also threats of social engineering by C, attempting to
   prevent A from giving rights to G which G legitimately deserves.

5.  IANA Considerations

   This document has no IANA Considerations.
