policies if any, to filter updates to the BGP speaker, thus reducing 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. That is, the router determines whether to carry ORF information in
messages, and if yes, whether to carry nonstandard 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
Follow these steps to enable the IPv6 MBGP ORF capability:
