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
.

Enable BGP route refresh for
a peer or a peer group.

ipv6-address
}
capability-advertise

Optional.
Enabled by default.
If this feature is not enabled, you
must configure this command.
5.
Enable the non-standard
ORF capability for a BGP
peer or a peer group.
peer
{
group-name

ipv6-address
}
capability-advertise orf

Optional.
By default, standard BGP ORF
capability defined in RFC 5291
and RFC 5292 is supported.
If this feature is not enabled, you
must configure this command.
