[Idr] draft on virtual aggregation

[Paul Francis <francis at cs.cornell.edu>]

Gang,

At the following URL is a draft on virtual aggregation that I'm posting to
IETF (it'll show up in a day or two), and which I'll present at IDR in
Dublin.  

 http://www.cs.cornell.edu/people/francis/draft-francis-idr-intra-va-00.txt

Title and abstract are below.  I hope to create a work item on this in IDR.
I would characterize this as falling under the general charter of scaling
BGP.

Any comments and discussion on this prior to Dublin is of course greatly
appreciated.

Title:  Intra-Domain Virtual Aggregation


   Virtual Aggregation (VA) is a technique for shrinking the DFZ FIB
   size in routers (both IPv4 and IPv6).  This allows ISPs to extend the
   lifetime of existing routers, and allows router vendors to build FIBs
   with much less concern about the growth of the DFZ routing table.  VA
   does not shrink the size of the RIB.  VA may be deployed autonomously
   by an ISP (cooperation between ISPs is not required).  While VA can
   be deployed without changes to existing routers, doing so requires
   significant new management tasks.  This document describes changes to
   routers and BGP that greatly simplify the operation of VA.
