Configuration Guide - IP Routing
Step 4 Run:
peer { group-name | ipv4-address } capability-advertise orf [ non-standard-
compatible ] ip-prefix { both | receive | send } [ standard-match ]
Prefix-based ORF is enabled for a BGP peer or peer group.
By default, prefix-based ORF is not enabled for a peer or peer group.
Step 5 Run:
peer { group-name | ipv4-address } ip-prefix ip-prefix-name import
A prefix-based import policy is configured for a peer or peer group.
----End
Checking the Configurations
After prefix-based BGP ORF is configured, you can run the following commands to check the
previous configuration.

<HUAWEI> display bgp peer 10.1.1.2 verbose
Issue 02 (2014-09-30)
NOTE
This step needs to be performed on both communication devices.
The ORF capability supported by non-Huawei devices may be different from that defined in the RFC
standard. To enable a Huawei device to communicate with a non-Huawei device, ensure that the devices
are configured with the same compatibility mode (either non-standard-compatible or RFC-compatible).
By default, the RFC-compatible mode is used.
BGP ORF has three modes: send, receive, and both. In send mode, a device can send ORF information. In
receive mode, a device can receive ORF information. In both mode, a device can either send or receive
ORF information. To enable a device to receive ORF IP-prefix information, configure the both or receive
mode on the device and the both or send mode on its peer.
NOTE
This step is performed only on the receiving device. An IP prefix list specified by ip-prefix-name must
have been configured. Otherwise, route filtering cannot be implemented. For details on IPv4 prefix list
configurations, see 10.2.2 Configuring an IPv4 Prefix
Run the display bgp peer [ ipv4-address ] verbose command to check prefix-based BGP
ORF negotiation information.
Run the display bgp peer ipv4-address orf ip-prefix command to check prefix-based BGP
ORF information received from a specified peer.
NOTE
The display bgp peer ipv4-address orf ip-prefix command must be run only on devices that have
sent routing information.
