Dissemination of Flow Specification Rules for IPv6
draft-ietf-idr-flow-spec-v6-04
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.

This document will redefine the [RFC5575] SAFIs in order to make them
AFI specific and applicable to both IPv4 and IPv6 applications.
