Route redistribution from ODR to RIP

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).

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 ODR:

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 a spoke.

Step 2: advertise the directly connected networks on the CPE3 router.

BS1No changes are required.

RIP configuration

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 thedirectly 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.

Command output analysis

Routing table
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.
