soft-reset is performed.
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 Table 84.
