Enabling the IPv6 MBGP ORF capability

The BGP Outbound Route Filter (ORF) feature enables a BGP speaker to send a set of ORFs to its BGP

peer 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, thus reducing the number of exchanged update

messages and saving network resources.
After you enable the 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 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 31
