The Resource Public Key Infrastructure (RPKI) to Router Protocol,
Version 2
draft-ymbk-sidrops-8210bis-00
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 them.
This document describes version 2 of the RPKI-Router protocol. RFC
6810 describes version 0, and RFC 8210 describes version 1. This
document updates RFC 8210.
