Abstract:

   This draft defines a new type of Outbound Route Filter (ORF), known
   as the Virtual Private Network (VPN) Prefix ORF.  The VPN Prefix ORF
   mechanism is applicable when VPN routes from different Virtual
   Routing and Forwarding (VRF) instances are exchanged through a single
   shared Border Gateway Protocol (BGP) session.The purpose of VPN
   Prefix ORF mechanism is to control the overload of VPN routes based
   on RT.  With this mechanism, the overload can be limited within the
   minimum range.
