Resource Public Key Infrastructure (RPKI) Router Implementation Report

Abstract

This document is an implementation report for the Resource Public Key Infrastructure (RPKI) Router protocol as defined in RFC 6810. The authors did not verify the accuracy of the information provided by respondents. The respondents are experts with the implementations they reported on, and their responses are considered authoritative for the implementations for which their responses represent. The respondents were asked to only use the "YES" answer if the feature had at least been tested in the lab.

1. Introduction

In order to formally validate the origin Autonomous Systems (ASes) of BGP announcements, routers need a simple but reliable mechanism to receive Resource Public Key Infrastructure (RPKI) [RFC6810] prefix origin data from a trusted cache. The RPKI Router protocol defined in [RFC6810] provides a mechanism to deliver validated prefix origin data to routers.

This document provides an implementation report for the RPKI Router protocol as defined in RFC 6810 [RFC6810].

The authors did not verify the accuracy of the information provided by respondents or by any alternative means. The respondents are experts with the implementations they reported on, and their responses are considered authoritative for the implementations for which their responses represent. Respondents were asked to only use the "YES" answer if the feature had at least been tested in the lab.

   +---------+-----+-----+-------+--------+---------+-----+------+-----+
   
   Note 1:  No, Error PDU gets silently ignored.

4. Protocol Sequence

Does the RPKI Router protocol implementation follow the four protocol sequences as outlined in Section 6 of [RFC6810]?

   S1:  Start or Restart
   
   S2:  Typical Exchange
   
   S3:  No Incremental Update Available
   
   S4:  Cache Has No Data Available
   
   +----+-----+-----+-------+--------+---------+------+--------+-------+
   |    | IOS |  XR | JUNOS |  rpki  |   rpki  | NCC  | RTRlib |  BBN  |
   |    |     |     |       |  .net  |   .net  |      |        |       |
   |    |     |     |       |  clnt  |   srvr  |      |        |       |
   +----+-----+-----+-------+--------+---------+------+--------+-------+
   | S1 | YES | YES |  YES  |  YES   |   YES   | YES  |  YES   |  YES  |
   | S2 | YES | YES |  YES  |  YES   |   YES   | NO~1 |  YES   |  YES  |
   | S3 | YES | YES |  YES  |  YES   |   YES   | YES  |  YES   |  YES  |
   | S4 | YES | YES |  YES  |  YES   |   YES   | YES  |  YES   | YES~2 |
   +----+-----+-----+-------+--------+---------+------+--------+-------+
   
   Note 1:  Does not implement Serial Query, thus Incremental Update is
            never available, so responds to Serial Query with Cache
            Reset as described in Section 6.3 of [RFC6810]
   
   Note 2:  Sends Cache Reset in response to Serial Query when no data;
            sends Error Report PDU in response to Reset Query when no
            data.

5. Protocol Transport

Does the RPKI Router protocol implementation support the different protocol transport mechanisms outlined in Section 7 of [RFC6810]?

   +---------+-----+-----+-------+-------+--------+-----+--------+-----+

   | Snd.5 | YES | YES |   NO  |  YES  |  YES   |  YES  |  YES   | YES |
   | Rcv.6 | --- | --- |  ---  |  ---  |  YES   | YES~1 |  ---   | YES |
   | Snd.6 | YES | YES |   NO  |   NO  |  ---   |  ---  |  YES   | --- |
   | Rcv.7 | --- | --- |  ---  |  ---  |  YES   | YES~1 |  ---   | YES |
   | Snd.7 | YES | YES |   NO  |   NO  |  ---   |  ---  |  YES   | --- |
   +-------+-----+-----+-------+-------+--------+-------+--------+-----+
   
   Note 1:  YES, but... fatal, so connection is dropped, but cache does
            not conclude it's inconsistent.

7. Incremental Updates Support

   |     |     |       |    clnt    |    srvr    |      |        |     |
   +-----+-----+-------+------------+------------+------+--------+-----+
   | YES | YES |  YES  |    YES     |    YES     | NO~1 |  YES   | YES |
   +-----+-----+-------+------------+------------+------+--------+-----+
