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.

RFC 7128            RPKI Router Implementation Report      February 2014
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.

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.

10.  Interoperable Implementations

List other implementations with which you have tested the interoperability of the RPKI Router implementation.

10.1.  Cisco Implementation

Cisco: The Cisco IOS and IOS-XR implementation should be interoperable with other vendor RPKI Router Protocol implementations. In particular, we have tested our interoperability with rpki.net's RPKI Router implementation.

10.2.  Juniper Implementation

Juniper: The Juniper Networks, Inc. JUNOS implementation should be interoperable with other vendor RPKI Router Protocol implementations. In particular, we have tested our interoperability with rpki.net's and NCC's RPKI Router Cache implementation.

10.3.  rpki.net Implementation

rpki.net: The rpki.net implementation should operate with other rpki- rtr implementations. In particular, we have tested our rpki-rtr server's interoperability with Cisco IOS, Cisco IOS-XR, and Juniper.

10.4.  RIPE NCC Implementation

RIPE NCC: The RIPE NCC validator has been tested by us with other rpki-rtr implementations. In particular, we have tested with RTRlib and CISCO IOS. We received positive feedback from close contacts who tested our validator with JUNOS and Quagga.

10.5.  RTRlib Implementation

RTRlib: The RTRlib has been tested by us with other rpki-rtr implementations. In particular, we have tested with rtr-origin from rpki.net and RIPE NCC Validator.

10.6.  BBN RPSTIR Implementation

BBN RPSTIR: We have not yet tested with any other implementations.

11.  Security Considerations

No new security issues are introduced to the RPKI Router protocol defined in [RFC6810].
