Final answer:
A manually configured route in a router's routing table is known as a static route. It directs traffic to a specified network not in the router's known routes and remains constant unless changed by an administrator.
Step-by-step explanation:
The type of route that is manually configured in a router's routing table and tells a router where to send traffic destined for a network not in the router's routing table is a static route. A static route is set up by an administrator and does not change unless manually updated. Static routes are used to ensure that network traffic follows a specific path through the network.
In contrast, a dynamic route is created by a routing protocol that automatically adjusts routes based on the current state of the network. A default route is a type of static route that tells the router where to send traffic if there is no specific route for a destination, acting as a gateway of last resort. A floating route is a static route with a higher administrative distance than dynamic routes, used as a backup route.
