These routes will be used to generate IPv6 BGP routesafter soft-reset is performed.Enabling the IPv6 BGP ORF capabilityThe BGP ORF feature allows a BGP speaker to send its BGP peer a set of ORFs through route-refresh messages. 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 andsaving network resources.After you enable the BGP ORF capability, the local BGP router negotiates the ORF capability withthe BGP peer through open messages (that is, determine whether to carry ORF information inmessages; 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 7.Follow these steps to enable the BGP ORF capability:To do… Use the command… RemarksStep 1 Enter system view system-view —Step 2 Enter BGP view bgp as-number RequiredStep 3 Enter IPv6 address familyview ipv6-family —Step 4 Enable BGP route refresh fora peer or peer grouppeer { group-name | ipv6-address }capability-advertise route-refreshRequiredEnabled by defaultStep 5 Enable the non-standard ORFcapability for a BGP peer orpeer grouppeer { group-name | ipv6-address }capability-advertise orf non-standardOptionalBy default, standardBGP ORF capabilitydefined in RFC5291 and RFC5292 is supported.
