.You have discovered that Router 8 on your network is not receiving updates from Router 10. Router10 has an IP address of 22.214.171.124. All routers run RIP. Since you are new and
not completely familiar with the topology of the network, you execute the debug ip rip command on Router 8 and receive the results shown below:
Router8# debug ip rip
