Hi Jim,
Thanks for your comments. The BGP Flowspec procedures is illustrated as following:

                                          EVPN FlowSpec Session                  EVPN FlowSpec Session
DDOS Detection Appliance--------------------------Egress PE-----------------------------Ingress PE------CE2
                                                                                         | 
                                                                                      CE1
DDOS Detection Appliance establishes EVPN flowspec session with Egress PE, it detects DDOS attack traffic and generate ACL rule, 
the ACL rule is announced to Egress PE through EVPN flowspec protocol, then the egress PE announces it to ingress PE, 
finally ingress PE installs the ACL rule for traffic filtering.
DDOS Detection Appliance only needs to support EVPN flowspec function, it doesn't need to support basic EVPN function.
Thanks
weiguo

Weiguo,

        I would like to better understand how a remote PE will "learn" that it needs to deliver a FS path to the ingress PE?? It cannot come from the CE as that is data plane learning. I would think that all FS paths have to be disseminated by a centralized controller.

A new version of I-D, draft-hao-idr-flowspec-evpn-00.txt
has been successfully submitted by Weiguo Hao and posted to the
IETF repository.

Name:           draft-hao-idr-flowspec-evpn
Revision:       00
Title:          Dissemination of Flow Specification Rules for EVPN
Document date:  2014-08-20
Group:          Individual Submission
Pages:          7
URL:            http://www.ietf.org/internet-drafts/draft-hao-idr-flowspec-evpn-00.txt
Status:         https://datatracker.ietf.org/doc/draft-hao-idr-flowspec-evpn/
Htmlized:       http://tools.ietf.org/html/draft-hao-idr-flowspec-evpn-00


Abstract:
   This document defines BGP flow-spec extension for Ethernet traffic
   filtering in EVPN network. A new BGP NLRI type (AFI=25, SAFI=TBD)
   value is proposed to identify EVPN flow-spec application. A new
   subset of component types and extended community also are defined.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
