A branch router is configured as an EIGRP stub. What is an expected effect of configuring a router as stub?

Configuring a router as an EIGRP stub prevents it from being a transit router for EIGRP traffic. Stub routers do not send DUAL queries to their neighbors for routes they don't originate, nor do they advertise routes learned from other EIGRP neighbors. This behavior is crucial for network stability and efficiency in spoke-and-hub topologies. By not receiving queries, the stub router reduces the scope of DUAL computations, preventing stuck-in-active (SIA) issues and improving convergence. The incorrect options describe behaviors that are not characteristic of an EIGRP stub router. A stub router does not advertise all learned external routes back to the hub; it typically only advertises its directly connected and summary routes. It also does not convert EIGRP routes to static routes. Lastly, EIGRP stub configuration does not automatically disable split-horizon; split-horizon is a separate mechanism.
