           Dissemination of Flow Specification Rules for IPv6
                     draft-ietf-idr-flow-spec-v6-05

Abstract

   Dissemination of Flow Specification Rules [RFC5575] provides a
   protocol extension for propagation of traffic flow information for
   the purpose of rate limiting or filtering.  The [RFC5575] specifies
   those extensions for IPv4 protocol data packets.

   This specification extends the current [RFC5575] and defines changes
   to the original document in order to make it also usable and
   applicable to IPv6 data packets.

1.  Introduction

   The growing amount of IPv6 traffic in private and public networks
   requires the extension of tools used in the IPv4 only networks to be
   also capable of supporting IPv6 data packets.

   In this document authors analyze the differences of IPv6 [RFC2460]
   flows description from those of traditional IPv4 packets and propose
   subset of new encoding formats to enable Dissemination of Flow
   Specification Rules [RFC5575] for IPv6.

   This specification should be treated as an extension of base
   [RFC5575] specification and not its replacement.  It only defines the
   delta changes required to support IPv6 while all other definitions
   and operation mechanisms of Dissemination of Flow Specification Rules
   will remain in the main specification and will not be repeated here.

2.  IPv6 Flow Specification encoding in BGP

   The [RFC5575] defines a new SAFIs (133 for IPv4) and (134 for VPNv4)
   applications in order to carry corresponding to each such application
   flow specification.
