Enabling the IPv6 BGP ORF capability
The BGP Outbound Route Filter (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. The local BGP router determines whether to carry ORF information
in messages. If yes, it will further determine 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 10 .
To enable the BGP ORF capability:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter IPv6 address family
view.
ipv6-family N/A
4. Enable BGP route refresh for a
peer or peer group.
peer { group-name |
ipv6-address } capability-advertise
route-refresh
Enabled by default.
5. Enable the non-standard ORF
capability for a BGP peer or
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.
6. Enable the ORF IP prefix
negotiation capability for a
BGP peer or peer group.
peer { group-name | ip-address |
ipv6-address } capability-advertise
orf ipv6-prefix { both | receive |
send }
Not supported by default.
