What is Stuck in active? how to explain it to anyone?

When EIGRP loses a route and there is no feasible successor the route will go from passive to active and the router starts sending queries to its neighbors.
EIGRP sends queries on all interfaces except the interface of the successor.Now there can be two things:-
(1)Neighbor has information about this particular route and will send information about it to router . The query process is now over.
(2)Neighbor don’t know anything about this route and will send a query themselves to their neighbors router.In this case neighbors will not send back reply until they recieve reply from their neighbors.

If case 2 will exist it means we are moving near to our answer.
Whenever a router send query it can wait for maximum three minutes for getting the reply.If reply is not recieved for more than 3 minutes.Router will announce that route to be stuck in active.
