The peer then applies the ORFs, in addition to its local routingpolicies (if any), to filter updates to the BGP speaker, thus reducing the number of exchanged Updatemessages and saving network resources.After you enable the BGP ORF capability, the local BGP router negotiates the ORF capability with theBGP peer through Open messages (that is, to determine whether to carry ORF information inmessages, and if yes, whether to carry non-standard ORF information in the packets). After completingthe negotiation process and establishing the neighboring relationship, the BGP router and its BGPpeer can exchange ORF information through specific route-refresh messages.For the parameters configured on both sides for ORF capability negotiation, see Table 6-2.Follow these steps to enable the BGP ORF capability:To do… Use the command… RemarksEnter system view system-view —Enter BGP view bgp as-number —Enable BGP route refresh for apeer/peer grouppeer { group-name | ip-address }capability-advertiseroute-refreshRequiredEnabled by default.Enable the non-standard ORFcapability for a BGP peer/peergrouppeer { group-name | ip-address }capability-advertise orfnon-standardOptionalBy default, standard BGP ORFcapability defined in RFC 5291and RFC 5292 is supported.If the peer supports onlynon-standard ORF, you need toconfigure this command.
