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

| 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.

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

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].
