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

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.
