![]() OSPF routing protocol has complete knowledge of network topology, allowing routers to calculate routes based on incoming requests. ![]() It effectively calculates the shortest path with minimum network traffic when the change occurs.įigure: OSPF Design and Terminology Pros and Cons of OSPF Protocol Pros: OSPF protocol best fits for complex networks that comprise multiple subnets working to ease network administration and optimize traffic. This occurs by creating a topology map for the network.Unlike RIP, OSPF only exchanges routing information when there’s a change in network topology. OSPF routing protocol collects link state information from routers in the network and determines the routing table information to forward packets. OSPF (Open Shortest Path First), a link-state routing protocol, is massively adopted in large enterprise networks. This causes packet loss and overloads network operations due to repeated processes. While using fixed hop count metrics to select the best routes, RIP fails to work when routes are compared based on real-time data. RIP doesn’t support multiple paths on the same route, which may generate more routing loops. When any link goes down it takes a lot of time to choose alternate routes. The hop counts of RIP are limited to 15 hops, so any router beyond that distance is considered infinity, and hence unreachable. ![]() Since any routing update in RIP will take up great bandwidth, the resources for critical IT processes are hence limited. RIP can create a traffic bottleneck as it broadcasts its updates every 30 seconds. RIP does not require an update every time the network topology changes. RIP routing is guaranteed to support almost all routers. RIP protocol is a great fit for small networks - It’s easy to understand and configure. It is clear that Path 2 will be selected by RIP protocol since it has fewer hop counts. Let’s take an example to see how RIP protocol works: Assuming, we have two paths available from the Source to the Destination. In RIP protocol, hop count is the only metrics to decide the best path to a remote network. RIP works to deliver the whole routing table to all active interfaces every 30 seconds. RIP (Routing Information Protocol), is an example of distance vector routing for local networks. RIP vs OSPF: What Is RIP Protocol in Networking? So, this blog will present a detailed description of these two routing protocols and key RIP vs OSPF differences. Network managers may find themselves in a dilemma when choosing between RIP vs OSPF. RIP (Routing Information Protocol) is one of the oldest routing protocols in service, whereas OSPF (Open Shortest Path First) serves as the most widely adopted IGP for large enterprise networks. The RIP protocol and OSPF protocol are two Interior Gateway Protocols (IGP) that intensively used in computer networks to specify the best routes for data transmission.
