A banking institution has a network configured based on the schema below. Each branch consists of one LAN and all routers were completely configured and in full working order. However, just after a Network Admin made changes to the BankB router -- users on the BankA and BankB LANs are unable to ping the BankC router. Please investigate and fix the problem. The routers have been configured with the following specifications: The routers are named BankA, BankB and BankC. RIP is the routing protocol. The clocking is provided on the Serial 0 interfaces. The secret password on all routers is "cisco". The subnet mask on all interfaces is the default mask.

Inside Tips: This question is very precise - you do not need to access any router other than BankB. (Everything was in working order prior to the changes on BankB) Write down the configs for BankB along with a brief outline of the question before you attempt to do anything. Also, note the password and the directly connected interface IP address on BankC. If you do not -- you will fall apart in the exam. Miss a Lab - you're in trouble. Miss two of them and you will not pass the CCNA Exam. Remember that "show running-config" is your friend and as always - save your work. End the Lab by verifying connectivity between BankB and BankC. Note: This Lab may show up on the exam where you would have to verify connectivity between BankA and BankC. The same logic applies but you would have to complete the task within at least two routers. To be successful - take an incremental approach - one router at a time.
