Three bicycle stores in the TestKing Pro chain have decided to establish network connectivity to maintain their repair business in a centralized manner. The stores contracted a local technician, non-Cisco  certified, to configure the routers. However, the local MCP certified technician was not able to finish the configuration in an appropriate manner. No network connectivity has been established among the  routers. The routers are named TestKing1, TestKing2, and TestKing3.  
TestKing Pro has contracted you to fix the problems. Identify the fault(s) and make the necessary  change(s) to establish connectivity. The routers have been configured with the following specifications:  
?The routers are named TestKing1, TestKing2, and TestKing3.  
?RIP is the routing protocol  
?Clocking is provided on the serial 0 interfaces  
?The password on each router is "testking"  
?The subnet mask on all interfaces is the default mask.  
?The IP addresses are listed in chart below.   
TestKing1  
E0 192.168.27.1  
E1 192.168.29.1  
S0 192.168.31.1  
Secret password: testking  
TestKing2  
E0 192.168.35.1
