Enabling the BGP ORF capability
The BGP Outbound Route Filtering (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 (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
.

3.
Enable BGP route refresh for a
peer or peer group.
peer
{
group-name

Enabled by default.
4.
Enable the non-standard ORF
capability for a BGP peer or
peer group.

ip-address
}
capability-advertise orf

Optional.
By default, standard BGP ORF
capability defined in RFC 5291
and RFC 5292 is supported.
If the peer supports only
non-standard ORF, you need to
configure this command.
