Lab 112: Route Redistribution between RIP and EIGRP

We will use the following topology to demonstrate how to perform redistribution between RIP and EIGRP. We assume that all devices have configured with appropriate IP addresses.

1.  Once you have configure IP addresses, execute the following commands to configure RIP routing on Router1.

Router1( config)# router rip 
Router1( config-router)# network 10.0.0.0 
Router1( config-router)# network 192.168.0.0
Router1( config-router)# exit

2.  Next, move on to Router2 and execute the following commands to configure RIP routing.

Router2( config)# router rip 
Router2( config-router)# network 192.168.0.0 
Router2( config-router)# exit

3.  Next, on Router2, execute the following commands to configure EIGRP routing.

 Router2( config)# router eigrp 100 
Router2( config-router)# network 192.168.1.0 
Router2( config-router)# exit

4.  The following figure shows the routing configuration of Router2.

5.  Next, move on to Router3 and execute the following commands to configure EIGRP routing.

Router3( config)# router eigrp 100 
Router3( config-router)# network 192.168.1.0 
Router3( config-router)# network 20.0.0.0 
Router3( config-router)# exit

6.  Next, move on to Router1 and execute the following command to show the routing table.

Router1# show ip route

7.  In the preceding figure, you can see that only Router1 has only the network routes of RIP routing protocol. It cannot learn EIGRP routes without until we perform the route redistribution.

Redistribute RIP into EIGRP

1.  To redistribute RIP into EIGRP, you need to execute the following commands on Router2.

Router2( config)# router rip 
Router2( config-router)# redistribute eigrp 100 metric 1

2.  The following figure shows the how to redistribute RIP routes into EIGRP on Router2.

Note: We recommend to have a close look up at the preceding figure to understand the syntax used to inject RIP routes into EIGRP.

Redistribute EIGRP into RIP

3.  To do so, execute the following commands on Router2.

Router2( config)# router eigrp 100 
Router2( config-router)# redistribute rip metric 10000 100 255 1 1500

4.  The following figure shows how to redistribute EIGRP routes into RIP.

Note: We recommend to have a close look up at the preceding figure to understand the syntax used to inject RIP routes into EIGRP.

5.  Once you have redistributed RIP into EIGRP and vice-versa, now, move on to Router1 and execute the following command to view the routing table.

Router1# show ip route

6.  Have you noticed any changes? Yes. In the preceding figure, you can see that 192.168.1.0/ 24 network is added.

7.  Next, move on to Router3 and execute the following command to view the routing table.

Router3# show ip route

8.  In the preceding figure, you can see that 10.0.0.0/ 8 and 192.168.0.0/ 24 networks are added through the external EIGRP protocol. That’s what actually does the Route Redistribution.
