> 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.
