Dissemination of Flow Specification Rules for IPv6
draft-ietf-idr-flow-spec-v6-20
Abstract
Dissemination of Flow Specification Rules I-D.ietf-idr-rfc5575bis
provides a Border Gateway Protocol extension for the propagation of
traffic flow information for the purpose of rate limiting or
filtering IPv4 protocol data packets.
This document extends I-D.ietf-idr-rfc5575bis with IPv6
functionality. It also updates I-D.ietf-idr-rfc5575bis by changing
the IANA Flow Spec Component Types registry.

1. Introduction
The growing amount of IPv6 traffic in private and public networks
requires the extension of tools used in IPv4-only networks to also
support IPv6 data packets.
