Enabling The Bgp Orf Capability - HP MSR2000 series Configuration Manual

Step
3. Disable BGP route-refresh and
multi-protocol extension capability for

5. Return to user view.
6. Perform manual soft reset on BGP
connections.

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
To enable the BGP ORF capability:
