RFC 8210 - The Resource Public Key Infrastructure (RPKI) to Router Protocol, Version 1

Authors: R. Bush (Internet Initiative Japan), R. Austein (Dragon Research Labs)

Status: Standards Track

Published: September 2017

Updates: RFC 6810

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 1 of the RPKI-Router protocol. RFC 6810 describes version 0. This document updates RFC 6810.
