A. B. C. D.

B

The correct answer is C. An aggregate route has a forwarding next hop that is inherited from a contributing route.

Explanation:

Generated and aggregate routes are two different types of routes that can be used in a routing table.

Generated routes are created by the router itself and are usually used for connected or static routes. They are created by the router when it has a directly connected interface or when a static route is configured. Generated routes have a forwarding next hop that is determined by the router's routing table.

Aggregate routes, on the other hand, are created by summarizing multiple routes into a single route. Aggregate routes are usually used to reduce the size of the routing table and to control the flow of traffic in the network. The forwarding next hop of an aggregate route is inherited from one of the contributing routes. This means that the next hop for the aggregate route will be the same as the next hop of one of the contributing routes.

Option A is incorrect because both generated and aggregate routes can be supernet routes. A supernet route is a route that covers multiple subnets or networks.

Option B is incorrect because the forwarding next hop of a generated route is not inherited from a contributing route. It is determined by the router's routing table.

Option D is incorrect because both generated and aggregate routes can be re-advertised through BGP using a policy. BGP policies can be used to control the advertisement of both types of routes.

Therefore, option C is the correct answer. An aggregate route has a forwarding next hop that is inherited from a contributing route.
