How can you test the connectivity and routing on a FortiGate device?

Testing connectivity and routing on a FortiGate device is commonly performed using the ping command. This command checks the reachability of a host on an Internet Protocol (IP) network by sending Internet Control Message Protocol (ICMP) Echo Request messages and waiting for Echo Reply messages. By sending these requests to a target IP address or hostname, the user can determine whether the target is reachable, assess the round-trip time for messages sent from the originating host to the target and back, and confirm that there is proper connectivity along the path.

In the context of FortiGate devices, using the ping command helps administrators troubleshoot network issues, verify if a specific target is online and responding, and validate the status of routing configurations. It serves as an essential first step in connectivity tests before delving into more complex troubleshooting methods.

While the traceroute command provides detailed path information for packets traveling to a destination and can reveal routing issues, it is more oriented towards analyzing paths through a network rather than directly confirming basic connectivity. The nslookup command is typically used for querying Domain Name System (DNS) records and resolving hostnames to IP addresses, while the netstat command displays network connections, routing tables, and other networking statistics but does not test connectivity in the same way as
