What is the purpose of the eigrp stub configurationcommand?

A.
to increase scalability by limiting the EIGRP queryrange

B.
to reduce the size of the routing table by blockingthe D EX (External EIGRP) routes into
the EIGRP stub router

C.
to reduce the convergence time by enabling the EIGRP stub router to propagate the
EIGRP queries from the EIGRP hub router

D.
to reduce the convergence time by enabling the EIGRP stub router to also perform query
requests to the EIGRP hub router

Explanation:
The EIGRP Stub Routing feature improves network stability, reduce resources utilization, and simplifies stub
router configuration.
Stub routing is commonly used in a hub and spoke network topology. You need to configure the distribution
(hub) and remote (spoke) routers to use EIGRP, and only the remote router as a stub. Only specified routes are
propagated from the stub router. The router responds to queries for summaries, connected routes, redistributed
static routes, external routes, and internal routeswith the message “inaccessible”. A stub router will send a
special peer information packet to all neighboring routers to report its status as a stub router.
Any neighbor that receives a packet informing it ofthe stub status will not query the stub router forany routes,
and a router that has a stub peer will not query that peer. The stub router will depend on the distribution router
to send the proper updates to all peers.
