Your customer network is running OSPF. An engineer has just finished network configuration. You are now tasked to check the configuration of the routers and answer some questions about the network operation. Because of security, “show running-config” commands are disabled on R1 and R5.
Note: You are not allowed to configure anything by company policy. The network is operating correctly so just use various “show” commands and “ping” to learn how this network works.
