OSPF does not have an upper limit for the number of hops.
Key Takeaway: OSPF is a link state protocol. Link state protocols do not use hops to mark networks as unreachable. They implement a steady state operation to their adjacent neighbors by periodically sending and receiving small Hello packets. If an OSPF router does not receive a Hello packet for a specified time period, it assumes that the neighbor is down. The router then runs the SPF algorithm to calculate new routes. At any cost, hop counts are not used.
