Which command can you enter to set the default route for all traffic to an interface?

The `ip route 0.0.0.0 0.0.0.0` command with an outgoing interface specifies that any traffic not matching a more specific route should be forwarded out of the GigabitEthernet0/1 interface, effectively setting the default route. This is the standard syntax for configuring a static default route in Cisco IOS.

A subnet mask of 255.255.255.255 (a host route) for a destination of 0.0.0.0 is syntactically incorrect and would not create a default route.

`default-information originate` is used within routing protocols (like OSPF or EIGRP) to inject a default route into the routing updates, not to configure a static default route directly on the router.

`default-information originate always` is also used within routing protocols to always advertise a default route, regardless of whether one exists in the local routing table, and does not configure a static default route.
