Task description
Let's look at an example of ODR configuration using the following scheme (Figure 1):
- wireless links are established between the BS1, CPE2 and CPE3 devices. BS1 is configured as Master and CPE2, CPE3 - as Slaves;
- each wireless device is connected to a wired network segment and each segment uses its own IP addressing;
- router R1 is also connected to LAN-3, as well as to the LAN-6, LAN-7, LAN-8 networks;
- it is necessary to establish connectivity between all the networks by configuring the ODR protocol on the BS1, CPE2 and CPE3 wireless devices.
Figure 1 - ODR configuration scheme
Solution
Let's perform a step by step configuration of the devices. In addition to the ODR configuration, in order to establish the communication with LAN-6, LAN-7 and LAN-8, static routing will be used (see Static routing).
The ODR configuration will be performed via CLI and after each step, the routing information will be displayed for analysis.
NOTE
An configuration example is given for the InfiLINK 2x2, InfiMAN 2x2 families devices, pay attention to the name of the radio interface on your devices during the scheme implementation.

Add static routes
The network segments LAN-6, LAN-7, LAN-8 are connected to router R1, while CPE3 does not have interfaces connected to these networks, so there is no routing information about these networks in its routing table. One way to fix this is to add static routes at CPE3 and at R1. Let's assume that the configuration of R1 has already been completed, so it is necessary to make changes to the configuration of CPE3.
Description | Add static routes for the LAN-6, LAN-7 and LAN-8 networks to CPE3's routing table. |

Exporting the static routes
In order to transmit the routing information about LAN-6, LAN-7 and LAN-8 to all the wireless devices, it is necessary to export the static records to ODR. This operation can be performed using CPE3's configuration, since the routing table of this device contains the static entries and the radio interface supports ODR.

ACL application
Filters can be applied to the routing information exported by the spoke devices. Let's look at some examples on how to filter the exported information.
Description | Configure the routing information filtering on CPE3 to allow the device to export only a static route to the 192.168.6.0/28 network. |

CPE3 | acl add $ODR net 192.168.6.0/28 mint rf5.0 -odr spoke kernel $ODR |
Description | Analyze the ODR's protocol operation at CPE3. The entries about the 192.168.7.0/28 and 192.168.8.0/28 networks have been removed from the exported routes list due to the filtering rule. The information about the 10.10.30.0/24 network is exported because the created filter was applied only to the static routes (kernel), and network 10.10.30.0/24 is directly connected. |
