There is no need for R1, R2, and R3 to forward RIP updates out of their LAN interfaces. The configuration in Figure 2 identifies the R1 G0/0 interface as passive. The show ip protocols command is then used to verify that the Gigabit Ethernet interface was passive. Notice that the G0/0 interface is no longer listed as sending or receiving version 2 updates, but instead is now listed under the Passive Interface(s) section. Also notice that the network 192.168.1.0 is still listed under Routing for Networks, which means that this network is still included as a route entry in RIP updates that are sent to R2.
