Disadvantages of OSPF algorithm

Explanation:
The SPF calculation is the central process here. OSPF uses the SPF algorithm to build a shortest-path tree from the router to every reachable node by examining the entire link-state database. As the network grows—more routers and links—the graph becomes larger, so the SPF run has more nodes and edges to evaluate. That leads to more CPU cycles and processing power required to recompute the paths, especially when topology changes are frequent. So the main drawback tied to the algorithm is that processing requirements increase with topology size, which can impact convergence time on busy networks unless hardware is scaled accordingly.
