To simulate a Routing Information Protocol (RIP) project using OPNET, we can follow below given steps. RIP is a distance-vector routing protocol utilized in local and broad area networks that depending on hop count like a routing metric and periodic updates handling the routing data.

Steps to Simulate Routing Information Protocol Projects in OPNET
- Set Up OPNET Environment
- Make a new project including a descriptive name in OPNET Modeler, and configure an appropriate workspace.
- Describe the network scale and first attributes, we require to replicate according to the network size and structure.
- Design Network Topology
- Make a network topology including routers and nodes, which can be supported RIP. In the topology, utilize IP Routers like the core devices.
- Organize the routers within a structure such as a mesh, tree, or ring topology in which routing is essential. Also we can associate end devices like LAN workstations to each router making traffic over the network.
- Enable RIP as the Routing Protocol
- In the network, choose every router and open their IP layer set up.
- Select RIP like the routing protocol in IP Routing Parameters.
- Set up RIP-specific metrics like:
- Update Interval: RIP transmits updates each 30 seconds by default. We need to modify this interval to learn their impacts on network performance.
- Route Aging Timer: Change it if we require routes to invalidate sooner or later than the default time.
- Set Up Traffic Sources
- In the network, we make applications to create traffic.
- In Application Configuration, append applications like FTP, HTTP, or Email, which will make network traffic.
- In Profile Configuration, describe profiles managing when and how frequently the traffic is made and then allocate them to certain source and destination nodes within the network.
- Configure Simulation Parameters
- Configure the simulation time to make sure that it is long sufficient to monitor several routing updates and the stabilization of routes.
- Allow data collection for performance parameters related to RIP, like:
- End-to-End Delay: Estimate the delay attaining its destinations for packets.
- Hop Count: Deliberates the amount of hops for every packet obtains.
- Route Convergence Time: Indicates how long it takes the network launching the stable routes.
- Traffic Sent and Received: Monitors throughput and traffic volume.
- Run the Simulation
- In OPNET, we can execute the simulation monitoring how RIP manages the routing updates and adapts to any modifications within the network.
- OPNET will indicate how RIP routers exchange routing tables occasionally and according to the hop counts update its routes.
- Analyze Results
- Analyse the RIP’s performance to utilize OPNET’s analysis tools:
- Route Convergence: Measure how rapidly RIP meets once there is a change such as a router attaining offline in the network.
- Packet Delivery Ratio: Try to find any dropped packets during route convergence, which may happen.
- Hop Count Distribution: For routes, examine the average hop count to observe if RIP effectively reduces hops.
- Routing Overhead: Deliberate the overhead triggered by updates periodically then estimate their influence on network performance.
- Experiment with Network Changes
- During the simulation, change the network like take a router offline monitoring how RIP manages route failures and recalculates paths.
- Experiment diverse network sizes and sets up to estimate the scalability and stability of RIP.
In this process, we had covered the details from the simulation set up to analyse the results of the Routing Information within OPNET tool. For further analysis or requirements, we will offer additional information of this process.
