If the successor path is lost & there is no feasible
successor path is available, router sends out query messages
on all EIGRP enable interfaces & tries to find out an
alternative path to the network. It is active state for that
route.

Now Router is waiting for reply from its neighbors. If reply
is missing for 3 min, dat means router didn't get any reply
from neighbors, then it becomes stuck in active.

In this case, router reset the neighbor relationship with
the router who didn't replied back the query messages sent
by the router.

To solve this problem, two method is used -

a) Router summarization
b) EIGRP Stub.

To disbale the stuck in active timer, the following command
is used -

Router(config-router)# timers active-time disable.
