Manually change OSPF cost

[CPRQ]

We manually change the cost from 1 to 200 but it did not change cost/metric to its neighbors. As default cost of OSPF interface is 1 and next hop/neighbor see the cost 2. We manually increase the default cost from 1 to 200, but it did not change the cost of next hop/neighbor cost; it still show cost 2. How can we increase the ospf cost so it trigger down to its neighbors.
