The command get router info routing-table all is the standard and most comprehensive FortiOS CLI command to display the complete Routing Information Base (RIB). This command lists all routes known by the FortiGate's routing daemon, including static routes, directly connected networks, and routes learned dynamically from protocols like OSPF, BGP, and RIP. It provides detailed information for each route, such as the protocol, distance, metric, and next-hop gateway, making it the primary tool for viewing and verifying the device's routing decisions.

diagnose netlink route list: This is a lower-level diagnostic command that displays the kernel's routing table, also known as the Forwarding Information Base (FIB), not the main routing daemon's RIB.

show router status: This is not a valid FortiOS command. The show command is used to display static configuration settings, not dynamic runtime information like the routing table.

get system route: This is not a valid FortiOS command for displaying the routing table. System-level information is retrieved via get system, but routing information is under the get router context.
