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.

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
