Enabling the 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, reducing 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, the BGP router determines whether to carry ORF information
in messages and, if so, whether to carry nonstandard 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 Table 8.
Follow these steps to enable the MBGP OR
