Which command is used to verify the hello and dead timer intervals on an OSPF interface?

The command that accurately verifies the hello and dead timer intervals on an OSPF interface is the one that specifies the interface directly, allowing for targeted examination of that particular interface's OSPF settings. In this case, using the command referring to a specific interface, such as "show ip ospf interface serial 0/0/0," provides detailed information about the OSPF parameters configured for that specific interface, including the hello and dead intervals.

By executing this command, it enables the network administrator to quickly check OSPF settings that are crucial for ensuring that OSPF neighbors can effectively communicate. The hello timer determines how often OSPF routers send hello packets to maintain neighbor relationships, while the dead timer specifies how long a router should wait without receiving a hello packet before declaring a neighbor down.

The broader command to display OSPF interface information does provide overall insights into OSPF configurations and will include these timers. However, by providing an interface name, the command focuses specifically on the parameters for that given interface, enhancing clarity and precision in troubleshooting or verification tasks.

Utilizing "show ip ospf interface" alone does not narrow down the context, potentially showing output for all OSPF interfaces and making it less convenient
