Which command configures a default route with gateway 192.168.1.254?

• A. /ip route set gateway=192.168.1.254
• B. /ip route add gateway=192.168.1.254
• C. /ip route add address=192.168.1.254
• D. /ip route create gateway=192.168.1.254

Answer: (B)

A default route directs all traffic destined for networks not in the local routing table to a single next hop. In RouterOS you create that route by adding a new route and specifying the gateway. The command /ip route add gateway=192.168.1.254 creates a route to 0.0.0.0/0 via 192.168.1.254, which is exactly how you establish a default gateway. Using set would only modify an existing route rather than create the new default path. Specifying address= would attempt to set the destination to the gateway itself, which isn’t how a default route is defined. The create form isn’t the correct way to define a route in this system.
