Enabling The Ipv6 Bgp Orf Capability - HPE 5800 Series Configuration Manual

Enabling the IPv6 BGP ORF capability

The BGP Outbound Route Filter (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 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 further determines 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
