    The Resource Public Key Infrastructure (RPKI) to Router Protocol
                draft-ietf-sidr-rpki-rtr-rfc6810-bis-05

Abstract

   In order to verifiably validate the origin Autonomous Systems and
   Autonomous System Paths of BGP announcements, routers need a simple
   but reliable mechanism to receive Resource Public Key Infrastructure
   (RFC 6480) prefix origin data and router keys from a trusted cache.
   This document describes a protocol to deliver validated prefix origin
   data and router keys to routers.

   This document describes version 1 of the rpki-rtr protocol.
