Use the "show ipintling 0/0" command to see the output of Split horizonis disabled,,.8. Passive-interface configurationThe RIP process also sends routing update packets to the loopback interface, which does not make any sense except for wasting resources.RlXconfig-router>^passive-interfaceloopback 0 k 168 /V Chapter 6 RIP*** I06 After setting Loopback0 as a passive interface, the interface no longer sends routing update packets outbound, but still receives routing update packets from other routers routing update packets from other routers. 9. unicast update In Figure 6-2-1, unicast updates are configured so that routers R1 and R2 can learn routes from each other, but neither will interact with R3 for routes. The reader can configure Rl, R2, and R3 in the CCNA simulation rack to verify the unicast update configuration. R1 is configured as follows: . Router>en Router#conft Router(config)#host R1 R1(config)#no cdp run R1(config)#int fa0/0 R1(config-if)#ip add 123.1.1.1 255.255.255.0 R1(config -if)#noshut R1 (config-if)#int loO R1(config-if)#ip add 1.1.1.1255.255.255.0 R1 (config-if)#router rip R1 (config-router)#net1.0.0.0 R1(config -router)#net123.0.0.0 R1(config-router)#passive-interface default This command sets all ports running the RIP protocol as passive ports , Loopback fa 0/0 is set as a passive interface , none of them send routing update packets out. If an interface needs to send routing update packets, then you can use no passive-interface and number to allow an interface to send routing update packets. R1(config-router)#neighbor 123.1.1.2 The neighbor command specifies 123.1.1.2 as a neighbor, and the routing update packets on R1 will be sent to the 123.1.1.2 router as unicast. R2 is configured as follows. Router>en Router#conft Router(config)#host R2 R2(config)#no cdp run R2(config)#int fa0/0 R2(config-if)#ip add 123.1.1.2 255.255.255.0 R2(config -if)#noshut R2(config-if)#intloO R2(config-if)#ip add 2.2.2.2255.255.255.0 R2(config-if)#router rip R2(config-router)#net2.0.0.0 R2(config -router)#net123.0.0.0 R2(config-router)#passive-interface default R2(config-router)#neighbor 123.1.1.1 R3 is configured as follows. Router>en Router#conft Router(config)#host R3 R3 (config)#no cdp run R3(config)tint fa0/0 R3(config-if)#ip add 123.1.1.3 255.255.255.0 R3 (config -if)#noshut R3 (config-if)#int loO R3(config-if)#ip add 3.3.3.3 255.255.255.0 R3(config-if)#router rip R3(config-router)#net3.0.0.0 169, iCCNA Study and Lab Guide . R3(config-router)#net123.0.0.0 R3(config-router)#passive-interface default Use the showiproute" command to view the routing tables of routers Rl, R2 and R3 respectively, you can find that R1 and R2 can learn each other's routes, but R3 cannot learn the routes on R1 and R2. Execute the "debugiprip" command on router R1 and you will see the following unicast update packet.
