ODR
...
configuration
Description | Configure the ODR protocol in accordance with the scheme.: Step 1: launch the ODR protocol on the rf5.0 radio interfaces of the BS2 and CPE3 routers. BS2 will be configured asa as hub role, CPE3 - as a spoke. Step 2: announce advertise the directly connected networks on the CPE3 router. |

|

| Start ODR:
mint rf5.0 -odr spoke
AnnounceAdvertise the directly connected networks:
mint rf5.0 -odr spoke connected |
|

OSPF
...
configuration
Description | Configure the OSPF protocol in accordance with the scheme.: Step 1: start the OSPF daemon on the BS1 and BS2 routers. Step 2: set routers 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: make redistribution of redistribute the directly connected networks on the BS2 router. During redistributing routes route redistribution from ODR, only the routes received from the devices with the 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 announce advertise the directly connected networks on BS2. |

Routing table
Description | Analyze the routing table on each device. The routing tables of the wireless devices contain entries that each device has information about each subnet shown in the scheme. This means that routes the route redistribution from ODR to OSPF were made was performed successfully. The 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. |
