A. B. C. D.CD
A generated route is a route that is created by summarizing or aggregating multiple routes into a single route. The following are the two correct statements about a generated route:
B. A generated route has a route preference of 150: Route preference is a value used by a router to select the best route among multiple routes to the same destination. In Junos OS, the default route preference for a generated route is 150, which is lower than the default preference of 170 for OSPF routes and 5 for static routes. This means that a generated route will be preferred over OSPF and static routes unless their preference is explicitly changed.
C. The primary contributing route is the route with the lowest preference that falls within the aggregate range of prefixes: When multiple routes are aggregated into a generated route, the primary contributing route is the route with the lowest preference that falls within the aggregate range of prefixes. This means that if two or more contributing routes have the same prefix length, the one with the lowest preference is selected as the primary contributing route. The primary contributing route is used to determine the next hop for the generated route.
Therefore, options B and C are the correct statements about a generated route. Options A and D are incorrect because a generated route does not require at least two contributing active routes to be active, and a generated route receives the next hop for the primary contributing route, not the next hop of the generated route itself.
