How to Implement eigrp protocol in OMNeT++

To implement the Enhanced Interior Gateway Routing Protocol (EIGRP) in OMNeT++, requirement to survey a sequences of stages to make an imitation model that help EIGRP. OMNeT++ is a great simulation encironment, we use INET framework, which spreads OMNeT++ with support for several network protocols.

Given below is the procedure to implement the EIGRP Protocol in OMNeT++.

Step-by-Step Implementations:

Step 1: Set Up OMNeT++ and INET

1. Install OMNeT++: To download and install the modest version of it from the official OMNeT++
2. Install INET Framework: To install and download INET framework well-suited with the OMNeT++ version from the INET repository.

Step 2: Understand EIGRP Protocol

EIGRP is a Cisco exclusive protocol that is castoff for powering routing conclusions and conformations on a computer network. Vital perceptions to know embrace:

• Hello packets: For neighbour finding.
• Update packets: For routing updates.
• Query and Reply packets: For searching for routes and responding to queries.
• ACK packets: For recognizing receipt of packets.

Step 3: Create EIGRP Module

1. Define EIGRP Module: To build a new module in OMNeT++ for EIGRP. This contain to making .ned and .cc/.h files.
2. Handle EIGRP Packets: To develop treatment for EIGRP packet types like Hello, Update, Query, Reply, and ACK.
3. Neighbor Discovery: Device the logic for discovering and continuing neighbour relationships.
4. Routing Table Management: To improve the logic for maintaining the routing table and route design.
5. Finite State Machine (FSM): Study by using FSM to manage the states of EIGRP like Neighbor Discovery, Route Calculation, etc.

Step 4: Integrate with INET Framework

1. Extend Routing Functionality: Spread the INET routing functionality to contain EIGRP.
2. Packet Format: Express the packet format for EIGRP packets inside the INET framework.
3. Simulation Model: Change or make network simulation models to include EIGRP-enabled routers.

Step 5: Simulation and Testing

1. Configure Network: Setting up a test network configuration by using the .ned files to express the network topology.
2. Simulation Parameters: State simulation parameters, together with the timing for hello packets, hold timers, etc.
3. Run Simulations: Accomplish simulations to test the actions of EIGRP under countless network conditions.
4. Analyze Results: Consider the results to validate the correct execution of the EIGRP protocol.

Step 6: Debug and Optimize

1. Debugging: By using the OMNeT++’s debugging tools to troubleshoot any problems in the EIGRP implementation.
2. Optimization: Adjust the EIGRP implementation for presentation and accuracy.

Example Implementation Outline

EIGRP.ned

simple EIGRP

{

parameters:

double helloInterval @unit(s) = default(5s);

double holdTime @unit(s) = default(15s);

gates:

input in[];

output out[];

}

EIGRP.cc

#include “EIGRP.h”

Define_Module(EIGRP);

void EIGRP::initialize()

{

helloInterval = par(“helloInterval”);

holdTime = par(“holdTime”);

scheduleAt(simTime() + helloInterval, new cMessage(“sendHello”));

}

void EIGRP::handleMessage(cMessage *msg)

{

if (strcmp(msg->getName(), “sendHello”) == 0)

{

sendHello();

scheduleAt(simTime() + helloInterval, msg);

}

else

{

// Handle other message types

}

}

void EIGRP::sendHello()

{

// Implementation of sending a hello packet

}

EIGRP.h

#ifndef __EIGRP_H_

#define __EIGRP_H_

#include <omnetpp.h>

using namespace omnetpp;

class EIGRP : public cSimpleModule

{

private:

double helloInterval;

double holdTime;

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

void sendHello();

};

#endif
