RIP vs. OSPF — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Published on February 2, 2024
RIP (Routing Information Protocol) uses distance-vector routing, simpler, slower convergence. OSPF (Open Shortest Path First) is a link-state protocol, more complex, faster convergence.

Key Differences
RIP and OSPF Routing Mechanisms: RIP (Routing Information Protocol) is a distance-vector routing protocol, using hop count as its primary metric. It is simpler and widely used in smaller networks. OSPF (Open Shortest Path First), on the other hand, is a link-state protocol that uses a more complex algorithm to calculate the shortest path based on various factors like bandwidth and link cost.
Scalability of RIP and OSPF: RIP is less scalable due to its limited hop count, typically up to 15, making it unsuitable for large networks. OSPF excels in scalability, efficiently managing large and complex networks with its ability to partition into areas and hierarchical routing.
Convergence Speed in RIP and OSPF: OSPF offers faster convergence compared to RIP. The convergence, which refers to the time a network takes to react to changes, is slower in RIP due to its periodic updates and time-based approach. OSPF quickly adapts to network changes using immediate state updates.
RIP and OSPF Network Overhead: RIP generates more network overhead in large networks due to its regular full routing table updates. OSPF reduces overhead by sending only incremental updates and using multicasting for routing information exchange.
Administrative Control in RIP and OSPF: In RIP, there is minimal administrative control over the path selection. OSPF provides more control over the routing process, allowing administrators to define the cost of each link, influencing the path selection.
