Abstract

A BGP [RFC4271] speaker can send Outbound Route Filters (ORFs) [RFC5291] 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.
