Dissemination of Flow Specification Rules for IPv6 Implementation Report
               draft-vandevelde-idr-ipv6-flowspec-imp-00

Abstract

   This document is an implementation report for the BGP Flow
   Specification Rules for IPv6 as defined in
   [I-D.ietf-idr-flow-spec-v6].  The respondents are experts with the
   implementations they reported on, and their responses are considered
   authoritative for the implementations for which their responses
   represent.

1.  Introduction

   In order to share Flow Specification Rules for IPv6 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
   Dissemination of Flow Specification Rules for IPv6 NLRI Format as
   defined in [I-D.ietf-idr-flow-spec-v6].

   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.

2.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" are to
   be interpreted as described in [RFC2119] only when they appear in all
   upper case.  They may also appear in lower or mixed case as English
   words, without any normative meaning.

5.  Interoperable Implementations

   Summary of executed Interop tests between different implementations

5.1.  Alcatel-Lucent - Cisco Systems

   This Interop test was between a Cisco IOS-XR router and a Alcatel-
   Lucent Router.  Between the two BGP devices an iBGP session is
   established.

   The following IPv6 Flow Specification NLRI is constructed using the
   Cisco router as IPv6 Flow Specification controller:

            !
            class-map type traffic match-all InteropMatchList
             match destination-address ipv6 2001:2::3/128
             match source-address ipv6 2002:2::3/128
             match destination-port 1-5 7-11 13-18 20-25 27-31
             match source-port 33-37 39-43 45-50 53-58 60-65
             match ipv6 icmp-type 35
             match ipv6 icmp-code 55
             match packet length 120-130 135-140 145-160 165-200 205-225
             match dscp 1-10 11-20 22-30 32-40 52-60
             match tcp-flag 240 any
             match protocol 6-71 73-80 85-90 95-105 110-115
             end-class-map
            !
            policy-map type pbr InteropCiscoAlu
             class type traffic InteropMatchList
              police rate 200 bps
              !
              redirect nexthop 2001::1
              set dscp 45
             !
             class type traffic class-default
             !
             end-policy-map


   This results with the following Flow Specification Extended
   communities and IPv6 Flow Specification NLRI:

   The above IPv6 Flow Specification rule is correctly received by the
   Alcatel-Lucent BGP speaker and is reflected as follows on the device:
