Let's look at an example of routing information redistribution from the ODR protocol to the RIP protocol using the scheme described in the main document (Figure 1).
Figure 1 - Route redistribution from ODR to RIP |
Description | Perform a preliminary configuration of the devices consisting of the following steps:
| |
---|---|---|
BS1 |
| |
BS2 |
| |
CPE3 |
|
Description | Configure ODR: Step 1: launch the ODR protocol on the radio interfaces of the BS2 and CPE3 routers. BS2 will be configured as hub, CPE3 - as a spoke. Step 2: advertise the directly connected networks on the CPE3 router. | |
---|---|---|
BS1 | No changes are required. | |
BS2 |
| |
CPE3 |
|
Description | Configure the RIP protocol: Step 1: start the RIP daemon on the BS1 and BS2 routers. Step 2: define the interfaces where OSPF should be started. Step 3: redistribute the routes from the ODR protocol. Such routes have a "kernel" type. Step 4: redistribute the directly connected networks on the BS2 router. It is necessary to announce at the BS1 router the route towards the loopback interface of the BS2 router. | |
---|---|---|
BS1 |
| |
BS2 |
| |
CPE3 | No changes are required. |
Description | Analyze the routing table on each device. The routing tables of the BS1 and BS2 devices are synchronized and contain entries about each subnet shown in the scheme. This means that the route redistribution from ODR to RIP was performed successfully. CPE3's routing table consists of routes towards the directly connected networks and a default route. This confirms the statement about the unidirectional redistribution. | |

Let's look at an example of routing information redistribution from OSPF to RIP using the scheme described in the main document (Figure 2).

BS1 |
| |
BS2 |
| |
CPE3 |
|
Description | Configure the OSPF protocol: Step 1: start the OSPF daemon on the BS1 and BS2 routers. Step 2: set the routers 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. | |

|
Description | Configure RIP on the BS1 and BS2 devices: Step 1: Start RIP on the routers. Step 2: define the interfaces through which routing information should be exchanged. Step 4: redistribute the routes from the OSPF protocol on BS2. Such routes have an "ospf" type. Step 4: redistribute the directly connected networks on the BS2 router. It is necessary to announce at the BS1 router the route towards the loopback interface of the BS2 router. | |
