Sorry for the confusion..I know that there are timers for eigrp,but that
is for neighbors not for routes.Eventhough eigrp is distance
vector(hybrid),unlike rip it don't have to holddown till the route gets
flushed out.Once the neighbor is down,it will look in the topology table
for feasible successor and add it to the routing table.That why thery
have faster convergence

EIGRP has hold timers!!!! If there was no hold timer and a neighbor
went down how would the EIGRP process change the route, or even know
that it was lost? In other words the route would never be "flushed" and
you would have a black hole, because EIGRP would be forwarding packets
to a "non existant"
route that's never been flushed. I suggest you read some docs. Start
here
