BGP Link-State Information Distribution Implementation Report
draft-ietf-idr-ls-distribution-impl-02

Abstract

This document is an implementation report for the BGP Link-State Information Distribution protocol. The editors 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. 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 share network link-state and traffic engineering information collected with external components using the BGP routing protocol a new BGP Network Layer Reachability Information (NLRI) encoding format is required.

This document provides an implementation report for the BGP Link-State Information Distribution NLRI Format as defined in [I-D.ietf-idr-ls-distribution].

The scope of the interoperability test is sucessful encoding and decoding of BGP-LS advertisements. No application specific logic has been verified.

The editors 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.

7. Interoperable Implementations

List other implementations that you have tested interoperability of BGP-LS Protocol Implementation.

7.1. Cisco Implementation

Cisco: The Cisco Systems, Inc. IOS-XR implementation should be interoperable with other vendor BGP-LS Protocol implementations. In particular, we have tested our interoperability with Juniper's JUNOS implementation.

7.2. Juniper Implementation

Juniper: The Juniper Networks, Inc. JUNOS implementation should be interoperable with other vendor BGP-LS Protocol implementations. In particular, we have tested our interoperability with the Cisco Systems, Inc. IOS-XR implementation and the Opendaylight implementation.

7.3. OpenDaylight Implementation

Opendaylight: The Opendaylight implementation should be interoperable with other vendor BGP-LS Protocol implementations. In particular, we have tested our interoperability with Juniper's JUNOS implementation and the Cisco Systems, Inc. IOS-XR implementation. BGP receiver is implemented in the OpenDaylight Hydrogen release. BGP sender functionality is planned in the upcoming Helium release.

8. IANA Considerations

This document makes no request of IANA.

Note to RFC Editor: The IANA has requested that this section remain in the document upon publication as an RFC. This note to the RFC Editor, however, may be removed.

9. Security considerations

No new security issues are introduced by the BGP Link-State Information Distribution Protocol defined in [I-D.ietf-idr-ls-distribution].
