How to start EIGRP Protocol Projects using OMNeT++

To create an Enhanced Interior Gateway Routing Protocol (EIGRP) project using OMNeT++ has includes the configuration for replication of environment and integrating or developing an EIGRP model and process the replications through appropriate settings. EIGRP is a distance-vector routing protocol through features of link-state routing, typically used in large-scale networks. OMNeT++ is a powerful replication tool that permits the modelling of networking protocols and while EIGRP is not natively implemented in OMNeT++ or the INET Framework, we can moreover execute the yourself or look for a previous for implementation to integrate your project.

Here’s a step-by-step guide on how to start an EIGRP simulation project in OMNeT++:

Steps to start EIGRP Protocol Projects using OMNeT++

  1. Install OMNeT++ and INET Framework

Already starting the EIGRP replication, create a certain OMNeT++ and the INET framework installed.

Steps to install OMNeT++:

  1. Download OMNeT++ from the official OMNeT++ website.
  2. Install OMNeT++ through following the instructions specific we your operating system. On Linux, we will use terminal commands we compile and on Windows we can use the Visual Studio.

Steps to install INET Framework:

  1. Download the INET Framework by cloning it from INET GitHub repository.
  2. Build INET using OMNeT++’s build system that integrates INET with OMNeT++.

git clone https://github.com/inet-framework/inet.git

cd inet

./configure

make

  1. Assure which INET is properly connected through OMNeT++ via setting the project in OMNeT++.
  1. Understand OMNeT++ Basics

OMNeT++ is based on a modular replication method:

  • Simple modules: They signify the individual network components like as routers, switches, and hosts.
  • Compound modules: These characterize a network consisting of interconnected simple modules.
  • NED files: These describe the network structure and connections among modules.
  • INI files: These are used to setting the replication for parameter metrices such as module setting, network setup, and simulation time.

Before execution is EIGRP, explain the yourself with these important components through exploring the samples for replication from OMNeT++ and INET.

  1. Check for EIGRP Implementation

Now, EIGRP is not natively supported in OMNeT++ or the INET framework, so we will require to:

  1. Use an existing EIGRP implementation such as if available in third-party repositories.
  2. Implement EIGRP yourself used the OMNeT++’s module-based framework for implement the EIGRP.

Option 1: Use an Existing EIGRP Implementation

If there is a third-party execution of EIGRP for OMNeT++, we can integrate it into your project:

  • Search GitHub or OMNeT++ forums for EIGRP estimations. we might detect the open-source code contributed through other researchers or developers.
  • Once we detect an execution, track the process we improve to your OMNeT++ environment.

Option 2: Implement EIGRP Yourself

EIGRP is a hybrid protocol associates the distance vector and link-state principles. If you’re creating the protocol yourself, your estimation will require to cover the following aspects:

  1. Neighbor Discovery: EIGRP routers method neighbour relationships through adjacent routers.
  2. Hello Packets: Routers periodically alter and Hello packets to handles the neighbour relationships.
  3. Routing Tables: Routers handles the routing tables and perform best-path measured.
  4. Reliable Transport Protocol (RTP): EIGRP uses RTP we enable the reliable communication for routing updates.
  5. Update and Query Mechanism: EIGRP routers send bring up-to-date packets when there is network modify and query packets to request the routing data.

In OMNeT++, you will state this component as modules:

  • Neighbor discovery as part of the router’s logic for the discovery.
  • Routing tables as data structures inside the router model for routing tables.
  • Hello and Update packets as communication exchanged among the routers.

We would require the describe a new simple modules and message types in OMNeT++ for EIGRP.

  1. Create the Network Topology

Once we have the EIGRP protocol executed or integrated, we require a generate the replication of the topology. This includes the state a network of routers, in which every router will process the EIGRP protocol.

Example NED File (Network Topology)

Here’s an example of how we can build a simple topology for an EIGRP replication:

network EIGRPSimulation {

submodules:

router1: EIGRPRouter {

@display(“p=100,100”);

}

router2: EIGRPRouter {

@display(“p=300,100”);

}

router3: EIGRPRouter {

@display(“p=500,100”);

}

connections:

router1.eth++ <–> router2.eth++;

router2.eth++ <–> router3.eth++;

}

Here, we describe the three routers such as router1, router2, and router3 connected through Ethernet connections. we can expand the topology has include the many routers or multiple kinds of connections based on your network model.

  1. Configure the Simulation in the INI File

The INI file permits we replicate the different parameters metrices for the replication, like as:

  • Router configuration: Involves the EIGRP parameters metrices such as hold time, hello interval, and another EIGRP-specific configuration.
  • Mobility: If we are replicating the mobile networks we can used the mobility models for routers such as random waypoint model.
  • Routing tables: we can set the initial routing tables or permits the protocol to dynamically bring up-to-date them.

Here’s an example configuration (omnetpp.ini):

[General]

network = EIGRPSimulation

sim-time-limit = 100s

# EIGRP Router configuration

*.router1.eigrp.as = 1

*.router1.eigrp.helloInterval = 5s

*.router1.eigrp.holdTime = 15s

*.router2.eigrp.as = 1

*.router2.eigrp.helloInterval = 5s

*.router2.eigrp.holdTime = 15s

# Mobility configuration for mobile nodes (optional)

*.router1.mobility = “RandomWaypointMobility”

*.router1.mobility.speed = 5m/s

*.router2.mobility = “RandomWaypointMobility”

*.router2.mobility.speed = 5m/s

# Recording and results

*.scalar-recording = true

*.vector-recording = true

This configuration file:

  • Configure the EIGRP AS (Autonomous System) number.
  • Setting the hello interval and hold time for the EIGRP routers.
  • Optionally set up the mobility for mobile routers.
  • Ensure the scalar and vector recording we seizure the replication data.
  1. Run the Simulation
  1. Build the simulation utilized their OMNeT++’s IDE or command-line tools (make).
  2. Launch the simulation moreover from the OMNeT++ IDE or via the command line.

For Sample, process the following command in the terminal:

./run -u Cmdenv -r EIGRPSimulation

  1. Monitor the simulation: utilized their observe OMNeT++’s built-in Tkenv graphical interface or Cmdenv for command-line output to track the replication.
  1. Analyze and Visualize Results

OMNeT++ permits you to visualize and analyse different aspects of the replication:

  • Routing tables: We can track the state of the routing tables to enable that EIGRP is correctly measure the routes.
  • Packet flow: Follow on the flow of EIGRP hello and bring up-to-date packets among routers.
  • Network performance: Record key parameter metrics such as packet delivery ratio, latency, and route convergence time.

Use scalar and vector recording we gather the data and plot graphs for comprehensive analysis.

  1. Extend and Experiment

Once the basic replication is process, we can extend the model by:

  • Adding more routers to validate the EIGRP scalability.
  • Simulating failures such as link failure or node failure to see how EIGRP maintain the topology changes.
  • Integrating with other protocols such as TCP or UDP we examine the EIGRP in many realistic network environments.

As a final point, we discussed about how to implement and process the Enhanced Interior Gateway Routing Protocol (EIGRP) project using OMNeT++ simulation tool clearly.
