OSPF design is an important network engineering knowledge both in real life Enterprise, Datacenter, Service provider networks, as well as any given certification exam.
Knowing OSPF itself will not help you to use it in the real life networks. Protocols always interact with each other and understanding and managing those interaction by keeping network complexity at the minimum distinguishes network designers from the network operators.
