Which command will display only direct routes?

`show route` displays all active routes in the routing table, not exclusively direct routes.

`show route inet.0 direct` is syntactically incorrect for filtering by protocol type; 'direct' is not a valid table option in this context.

`show ip route direct` is a command used in Cisco IOS, not Juniper OS, and the correct Cisco command for directly connected routes is `show ip route connected`.

In Juniper OS, the `show route protocol direct` command filters the routing table to display only routes that have been learned directly from the router's interfaces, categorized under the 'direct' protocol.
