Route redistribution from ODR to OSPF
Let's look at an example of routing information redistribution from the ODR protocol to the OSPF protocol, using the network scheme described in the main document (Figure 1).

Pre-configuration
Description | Perform a preliminary configuration of the devices, consisting of the following steps: - Configure the device IDs.
- Remove the svi1 interface.
- Assign IP addresses to the network interfaces, according to the scheme.
- Disable switching.
- Establish the wireless links.

ODR configuration
Description | Configure the ODR protocol: Step 1: launch the ODR protocol on the rf5.0 interfaces of the BS2 and CPE3 routers. BS2 will be configured as hub, CPE3 - as spoke. Step 2: advertise the directly connected networks on the CPE3 router. |
---|
BS1 | No changes are required. |
---|
BS2 | Code Block |
---|
| Start ODR:
mint rf5.0 -odr hub |
|
---|
CPE3 | Code Block |
---|
| Start ODR:
mint rf5.0 -odr spoke
Advertise the directly connected networks:
mint rf5.0 -odr spoke connected |
|
---|
OSPF configuration
Description | Configure the OSPF protocol: Step 1: start the OSPF daemon on the BS1 and BS2 routers. Step 2: set the router IDs. The identifiers will be equal to the IP addresses assigned to the loopback interface. Step 3: define the interfaces where OSPF should be started. Step 4: redistribute the routes from the ODR protocol. Such routes have a kernel type. Step 5: redistribute the directly connected networks on the BS2 router. During route redistribution from ODR, only the routes received from the devices having a spoke role will be imported. Thus, to transmit routing information about the networks 172.16.2.0/29 and 192.168.0.2/32, it is necessary to advertise the directly connected networks on BS2. |

Command output analysis
Routing table
Description | Analyze the routing table on each device. The routing tables of the wireless devices contain entries about each subnet shown in the scheme. This means that the route redistribution from ODR to OSPF was performed successfully. CPE3's routing table consists of the routes to the directly connected networks and a default route. This confirms the statement about the unidirectional redistribution. |
