 RPKI Autonomous Systems Cones: A Profile To Define Sets of Autonomous
              Systems Numbers To Facilitate BGP Filtering
                    draft-ietf-grow-rpki-as-cones-02

Abstract

   This document describes a way to define groups of Autonomous System
   numbers in RPKI [RFC6480].  We call them AS-Cones.  AS-Cones provide
   a mechanism to be used by operators for filtering BGP-4 [RFC4271]
   announcements.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

1.  Introduction

   The main goal of the Resource Public Key Infrastructure (RPKI) system
   [RFC6480] is to support improved security for the global routing
   system.  This is achieved through the use of information stored in a
   distributed repository system comprised of signed objects.  A
