  * 4) Destination Preference Attribute (DPA)
  * 
  * 	(draft-ietf-idr-bgp-dpa-05.txt
  * 	 draft-ietf-idr-dpa-application-02.txt

  * 	The processing of the the DPA value is currently
  * 	included in the route policy calculation as:
  * 
  * 	Multi-Exit-Discriminator (MED)  - 1st
  * 	Destination Preference Attribute (DPA) - 2nd 
  * 	 
  * 	Cisco and RsD implement the preference in that
  * 	way.  Discussions will continue offline and a
  * 	new internet draft will capture joint agreement of
  * 	current authors and implementors.  Watch your mailing
  * 	list for an announcement of this document.

Consensus has been reached ;-). Document should be coming as soon as
the internet-draft announcement makes it out of cnri. Here's the
changed piece of text regarding route selction....

   A router may use DPA to influence LOCAL_PREF computation. DPA shall
   not directly affect route selection.
 
   DPA influence of the LOCAL_PREF attribute computation is a local
   matter. In general a route with a higher DPA indicates a higher
   preference by the originator of the DPA attribute.
....

Also, other bits for the minutes. It was agreed that once the change
to the document was made to move dpa to PS and the two associated
documents to Informational.
 
  * 5) BGP communities
  * 	
  * 	-draft-chandra-bgp-communities-00.txt
  * 
  * 	The BGP community specification has been release for
  * 	over a year. It has been implemented
  * 	by Bay networks and Cisco.  It is suggested that
  * 	Yakov make the last call, and move it to proposed standard. 
  * 
  * 
  * 	Tony Bates and Enke Chen has released a draft
  * 	on the usage of communities.  Enke Chen made a presentation
  * 	of this feature at the NANOG meeting in February 1996.
  * 	[draft-bgp-communities-00.txt)
  * 	(The editor needs the draft name of the document.)
  *
It is known as 

	draft-chen-community-usage-00.txt
	
As noted in the meeting this will be changed to an idr document and then
published as informational. The idr document has already been sent to
the internet-drafts folks.

  * 6) BGP Confederations
  * 
  * 	draft-trainia-bgp-confed-00.txt
  * 
  * 	It was moved that is be moved to experimental.
  * 	In deployment Cisco discovered some problems with
  * 	this approach.
  * 
  * 7) Route Reflection
  * 
  * 	draft-bates-route-reflect-00.txt
  * 	
  * 	Cisco has implemented the route reflection a year ago.
  * 	MCI has used this in it's network for a year.
  * 	(Has Bay implemented this?) 	
  *
Also it has to be turned into an idr document which I've also snet in.
 	 
  * 	The working group recommends that this move forward to 
  * 	experimental.  A work item for the group is to
  * 	decide which solution to the IBGP mesh problem will
  * 	be selected by the group: the Route Reflection 
  * 	or the Route Server (Dimitry Haskins) or a cobmination
  * 	of both. 
  *
