CISCO CCNA Exam – Q153

If the router Cisco returns the given output and has not had its router ID set manually, what value will OSPF use as its router ID?


Correct Answer: D

If a router-id is not configured manually in the OSPF routing process the router will automatically configure a router-id determined from the highest IP address of a logical interface (loopback interface) or the highest IP address of an active interface. If more than one loopback interfaces are configured, the router will compare the IP addresses of each of the interfaces and choose the highest IP address from the loopbacks.
