How to Start EIGRP Protocol Projects Using NS3

To start EIGRP in NS3 does not inherently support EIGRP (Enhanced Interior Gateway Routing Protocol) because it mainly concentrates on open standard protocols instead of proprietary ones such as EIGRP that is Cisco-specific. However, there are several techniques available to simulate or approximate behaviour of EIGRP in NS3. Given below are some potential methods:

Steps to Start EIGRP Protocol Projects in NS3

Approach 1: Simulate EIGRP with Static Routing and Custom Metrics

This method includes configuring static routes with tailored metrics to mimic EIGRP-like behavior. Although it does not completely replicate the dynamic nature of EIGRP, it can be helpful for small scale, and static network simulations.

  1. Create a New Script for EIGRP-Like Simulation
  1. In NS3, we need to create a new file named eigrp_simulation.cc within the scratch directory.
  2. Configure a simple topology including static routing and custom metrics utilising the below given code:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/ipv4-static-routing-helper.h”

#include “ns3/point-to-point-module.h”

using namespace ns3;

int main(int argc, char *argv[]) {

// Enable logging for demonstration purposes

LogComponentEnable(“EigrpSimulation”, LOG_LEVEL_INFO);

// Create nodes

NodeContainer nodes;

nodes.Create(4);  // Example with 4 nodes to simulate a small network

// Set up point-to-point links

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“1Gbps”));

pointToPoint.SetChannelAttribute(“Delay”, StringValue(“10ms”));

// Install links between nodes to form a topology

NetDeviceContainer devAB = pointToPoint.Install(nodes.Get(0), nodes.Get(1));

NetDeviceContainer devBC = pointToPoint.Install(nodes.Get(1), nodes.Get(2));

NetDeviceContainer devCD = pointToPoint.Install(nodes.Get(2), nodes.Get(3));

NetDeviceContainer devDA = pointToPoint.Install(nodes.Get(3), nodes.Get(0));

// Install Internet stack

InternetStackHelper internet;

internet.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

Ipv4InterfaceContainer ifacesAB = ipv4.Assign(devAB);

ipv4.SetBase(“10.1.2.0”, “255.255.255.0”);

Ipv4InterfaceContainer ifacesBC = ipv4.Assign(devBC);

ipv4.SetBase(“10.1.3.0”, “255.255.255.0”);

Ipv4InterfaceContainer ifacesCD = ipv4.Assign(devCD);

ipv4.SetBase(“10.1.4.0”, “255.255.255.0”);

Ipv4InterfaceContainer ifacesDA = ipv4.Assign(devDA);

// Use static routing to approximate EIGRP behavior

Ipv4StaticRoutingHelper staticRoutingHelper;

Ptr<Ipv4> ipv4A = nodes.Get(0)->GetObject<Ipv4>();

Ptr<Ipv4StaticRouting> staticRoutingA = staticRoutingHelper.GetStaticRouting(ipv4A);

staticRoutingA->AddNetworkRouteTo(Ipv4Address(“10.1.3.0”), Ipv4Mask(“255.255.255.0”), Ipv4Address(“10.1.1.2”), 1);

Ptr<Ipv4> ipv4B = nodes.Get(1)->GetObject<Ipv4>();

Ptr<Ipv4StaticRouting> staticRoutingB = staticRoutingHelper.GetStaticRouting(ipv4B);

staticRoutingB->AddNetworkRouteTo(Ipv4Address(“10.1.4.0”), Ipv4Mask(“255.255.255.0”), Ipv4Address(“10.1.2.2”), 1);

Ptr<Ipv4> ipv4C = nodes.Get(2)->GetObject<Ipv4>();

Ptr<Ipv4StaticRouting> staticRoutingC = staticRoutingHelper.GetStaticRouting(ipv4C);

staticRoutingC->AddNetworkRouteTo(Ipv4Address(“10.1.1.0”), Ipv4Mask(“255.255.255.0”), Ipv4Address(“10.1.3.1”), 1);

Ptr<Ipv4> ipv4D = nodes.Get(3)->GetObject<Ipv4>();

Ptr<Ipv4StaticRouting> staticRoutingD = staticRoutingHelper.GetStaticRouting(ipv4D);

staticRoutingD->AddNetworkRouteTo(Ipv4Address(“10.1.2.0”), Ipv4Mask(“255.255.255.0”), Ipv4Address(“10.1.4.1”), 1);

// Run the simulation

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Build and Run the Simulation
  1. In the NS3’scratch folder to save eigrp_simulation.cc.
  2. Go to a terminal, pass through to the NS3 directory, and then make the script:

./ns3 build

  1. Run the simulation:

./ns3 run scratch/eigrp_simulation

Approach 2: Interface NS3 with an External Routing Software

To exactly simulate the EIGRP, we can integrate NS3 including external network emulation software such as Cisco’s GNS3 or Quagga, it is an open-source routing software which supports other protocols however it does not directly support EIGRP. Following is a high-level outline of this process:

  1. Install GNS3: GNS3 is a network emulation tool, which can be executed Cisco devices with EIGRP sets up.
  2. Connect NS-3 and GNS3: We can be associated NS3 nodes to a virtual network interface, which interacts with GNS3 nodes executing in Cisco EIGRP.
  3. Configure EIGRP on GNS3: Set EIGRP using GNS3 on Cisco routers. NS3 will transfer traffic to the GNS3 simulation in which EIGRP can be comprehensively used.

This method needs to configure a virtual interface among the NS3 and GNS3 that frequently utilize TAP bridges or same virtual networking methods.

Approach 3: Implement EIGRP Logic in NS3 (Advanced)

If we have in-depth knowledge of EIGRP and NS3 then we should execute an EIGRP module from scratch within NS3. It includes coding mechanisms of EIGRP such as:

  • Neighbour discovery and maintenance.
  • To use metrics for distance vector table updates.
  • Divide horizon and route poisoning, avoiding routing loops.
  • For route selection, viable successor calculation.

This setup outlines the simulation approaches and includes sample snippets designed to replicate and implement the EIGRP Protocol projects using NS3 environment. We can ready to prepare further details on this topic as required.
