Enabling the IPv6 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, thus reducing the number of exchanged update
messages and saving network resources.
After you enable the ORF capability, the local BGP router negotiates the ORF capability with the BGP
peer through open messages. That is, the 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 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 14.

4. Enable BGP route refresh for a
peer or a peer group.
peer { group-name |
ipv6-address } capability-advertise
route-refresh
Optional.
Enabled by default.
If this feature is not enabled, you
must configure this command.
5. Enable the non-standard ORF
capability for a BGP peer or a
peer group.
peer { group-name |
ipv6-address } capability-advertise
orf non-standard
Optional.
By default, standard BGP ORF
capability defined in RFC 5291
and RFC 5292 is supported.
If this feature is not enabled, you
must configure this command.
6. Enter IPv6 MBGP address
family view.
ipv6-family multicast N/A
7. Enable the ORF IP prefix
negotiation capability for a
BGP peer or a peer group
peer { group-name |
ipv6-address } capability-advertise
orf ip-prefix { both | receive |
send }
Not enabled by default.
