Enabling the MBGP ORF Capability
The BGP Outbound Route Filter (ORF) feature allows a BGP speaker to send to 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, thus 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 (that is, determine whether to carry ORF information in messages;
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, refer to Table 8-1 .
Follow these steps to enable the MBGP ORF capability:
