• Lab 4-1 Redistribution Between Eigrp And Ospf

Router(config)#router ospf 1Router(config-router)#area 1 range 192.168.10.0 255.255.255.0Since OSPF does not summarize automatically, you do not need the no auto-summary command here.Redistributing RoutesIn Chapter 4, you were introduced to redistribution. The CCNA exam requires you to have a keen knowledge of redistribution. In particular you are required to know how to redistribute routes in RIP and this sections looks at that. For this section, the network shown in Figure 5-12 will be used.In the network shown in Figure 5-12, RIPv2 is running on RouterA and RouterB while EIGRP is running on RouterB and RouterC. RouterA has no route towars 172.16.0.0/16 network that is being advertised by EIGRP.Figure 5-12 Redistributing RoutesAs you know from Chapter 14, while redistributing routes into a protocol, the metric compatibility much be ensured. In this case, routes to 172.16.0.0/16 will have EIGRP metrics and those tend to be large numbers. On the other hand, anything above 15 is an invalid metric for RIP.

To overcome this, RIP must be told what metric to assign to the routes redistributed from EIGRP. To redistribute the routes, the redistribute protocol process-id metric metric command is used in the routing protocol configuration mode. To redistribute EIGRP routes into RIP in the given network, the following commands are required on RouterB.
