OSPF totals the OSPF cost of every outgoing interface in an end-to-end route to determine the route's cost. OSPF then chooses the route with the lowest cost as the best route to a subnet.
This video gives you a scenario that requires you to puzzle through and recreate some of the OSPF logic to calculate the cost of different routes in an Enterprise network. You need to consider which interfaces and OSPF cost settings impact the cost of three different routes. You then need to reconfigure the routers so that the results show routes with the requested total OSPF cost.
