The peer then applies the ORFs, in addition to its local routing policies (if any), to filter updates to the BGP speaker, reducing the number of exchanged update messages and saving network resources. After you enable the BGP ORF capability, the local BGP router negotiates the ORF capability with the BGP peer through Open messages. The local BGP router determines whether to carry ORF information in messages. If yes, it will further determine whether to carry non-standard ORF information in the packets. After completing the negotiation process and establishing the neighboring relationship, the BGP router and its BGP peer can exchange ORF information through specific route-refresh messages. For the parameters configured on both sides for ORF capability negotiation, see Table 6. To enable the BGP ORF capability: Step Command Remarks 1. Enter system view. system-view N/A 2.
