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 13 .
Follow these steps to enable the IPv6 MBGP ORF capability:

By default, standard BGP ORF
capability defined in RFC 5291
and RFC 5292 is supported.
