Enabling The Mbgp Orf Capability - HP A8800 Configuration Manual

Step
7. Soft-reset MBGP connections
manually.

Enabling the MBGP ORF capability

The MBGP Outbound Router Filter (ORF) feature enables an MBGP speaker to send a set of ORFs to its
MBGP 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 MBGP speaker, thus reducing the number of exchanged
update messages and saving network resources.
After you enable the ORF capability, the local MBGP router negotiates the ORF capability with the
MBGP peer through Open messages. That is, the MBGP 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 MBGP router and
its MBGP 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 MBGP ORF capability:
Step
1. Enter system view.
2. Enter BGP view.
3. Enable BGP route refresh for a
peer/peer group.
4. Enable the non-standard BGP
ORF capability for a BGP
peer/peer group.
5. Enter MBGP address family
view.
6. Enable the ORF IP prefix
negotiation capability for an
MBGP peer/peer group.
