BGP4の新しい属性の提案です。既にCiscoのβ版ではリリースされているとのことで
す。マルチホームを行った場合に帰りのパケットがどちらのルートを経由してくるか
を制御できます。ぜひ、試験系に入れてみて商用化後に当社の顧客に利用を勧めたい
と思います（マルチホームをする人がインストールする必要あり）。
とにかく、読んでおいて下さい。


This basically has one change which is the type code to 11 from 10. 
As agreed at the IDR meeting in Stockholm, as soon as we have two 
implentations with DPA we will be requesting this to be a PS RFC
and the other two associated documents as follows:-

1) draft-ietf-idr-symm-multi-prov-01.txt as Informational
2) draft-ietf-idr-dpa-application-01.txt as BCP (IESG willing of course)

        Regards,
                --Tony.

A Revised Internet-Draft is available from the on-line Internet-Drafts 
directories. This draft is a work item of the Inter-Domain Routing Working 
Group of the IETF.                                                         

       Title     : Destination Preference Attribute for BGP                
       Author(s) : E. Chen, T. Bates
       Filename  : draft-ietf-idr-bgp-dpa-02.txt
       Pages     : 4
       Date      : 08/01/1995

The Border Gateway Protocol [1] is an inter-autonomous system routing 
protocol designed for TCP/IP internets.    
                                
This document describes a new BGP path attribute termed "Destination 
Preference Attribute" (DPA) which can be used by a single autonomous system
(AS) to specify globally transitive metrics in its routing announcement via
BGP.  The metric can then be used by upstream BGP speakers to favor certain
path for return traffic.  The application of this attribute includes 
facilitating the implementation of symmetric routing and load sharing in 
the multi-provider Internet.

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-ietf-idr-bgp-dpa-02.txt".
                                                        
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
                                                        
For questions, please mail to [e-mail].
                                                        

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
