Technical Summary

  A BGP speaker can send Outbound Route Filters (ORF) to a peer.  The
  peer uses ORFs to filter routing updates that it sends to the BGP
  speaker.  Using ORF, a BGP speaker can realize a "route pull"
  paradigm, in which the BGP speaker, on demand, pulls certain routes
  from the peer.

  This document defines a new Outbound Route Filter (ORF) type, called
  the "Covering Prefixes ORF (CP-ORF)".  CP-ORF is applicable in
  Virtual Hub-and-Spoke VPNs.  It also is applicable in BGP/MPLS
  Ethernet VPN (EVPN) networks.
