A is correct because generated routes require a contributing route. A contributing route is a route that matches the destination prefix of the generated route and has a valid next hop 1 . A generated route is only installed in the routing table if there is at least one contributing route available 2 . This ensures that the generated route is reachable and useful. If there is no contributing route, the generated route is not added to the routing table 2 .
B is correct because generated routes show a next hop in the routing table. A generated route inherits the next hop of its primary contributing route, which is the most preferred route among all the contributing routes 2 . The next hop of the generated route can be either an IP address or an interface name, depending on the type of the contributing route 2 . The next hop of the generated route can also be modified by a routing policy 3 .
