It depends on what caused the problem. If a local serial link fails, a
router can start the convergence process immediately if it notices the
Carrier Detect (CD) signal drop. On an Ethernet network, if the router's
own transceiver fails, it can start the convergence process immediately.
Otherwise, the router starts the convergence process after three x the
5-second hello timer (15 seconds).
When an EIGRP router detects that a link has failed or that a neighbor
router isn't sending hellos any more, if a feasible successor has an
alternate route, the router switches to the alternate route immediately,
without causing any network traffic. If there is no successor, the router
sends a query to neighbors. The query propagates across the network until a
new route is found. That could take a few seconds that may have to be added
to the 15 seconds already mentioned.
