How to Start Routing Information Protocol projects using NS3

To create the Routing Information Protocol (RIP) is a distance-vector routing protocol which utilized the hop count as a metric. The NS3 involves to support the RIP and creating it straightforward to replicate the RIP-based routing scenarios.

Steps to Start Routing Information Protocol projects using NS3

  1. Set Up NS3
  1. Install NS3:

sudo apt update

sudo apt install g++ python3 git cmake

git clone https://gitlab.com/nsnam/ns-3-dev.git

cd ns-3-dev

./waf configure

./waf build

  1. Verify Installation:

./waf –run scratch/my-first

  1. Plan Your RIP Simulation
  1. Define Network Topology:
    • We generate a simple or complex topology for utilized the NS3’s Node Container and Point to Point Helper.
  2. Configure RIP:
    • Utilized the Rip Helper to ensure the RIP on specific nodes.
  3. Add Traffic:
    • Replicate the data flow among nodes utilized their applications such as UDP or TCP.
  1. Basic RIP Example

The following steps for sample validate how to set up a network with RIP routing enabled.

Example Code:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

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

#include “ns3/applications-module.h”

using namespace ns3;

int main() {

// Create nodes

NodeContainer nodes;

nodes.Create(4);

// Create point-to-point links

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“10Mbps”));

pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));

NetDeviceContainer devices1 = pointToPoint.Install(nodes.Get(0), nodes.Get(1));

NetDeviceContainer devices2 = pointToPoint.Install(nodes.Get(1), nodes.Get(2));

NetDeviceContainer devices3 = pointToPoint.Install(nodes.Get(2), nodes.Get(3));

// Install Internet stack

InternetStackHelper stack;

RipHelper ripRouting;

// Assign RIP to nodes

Ipv4ListRoutingHelper listRouting;

listRouting.Add(ripRouting, 0);

stack.SetRoutingHelper(listRouting);

stack.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

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

ipv4.Assign(devices1);

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

ipv4.Assign(devices2);

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

ipv4.Assign(devices3);

// Create traffic

uint16_t port = 9;

UdpEchoServerHelper echoServer(port);

ApplicationContainer serverApps = echoServer.Install(nodes.Get(3)); // Node 3 as server

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

UdpEchoClientHelper echoClient(Ipv4Address(“10.1.3.1”), port); // Node 0 as client

echoClient.SetAttribute(“MaxPackets”, UintegerValue(5));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));

echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));

ApplicationContainer clientApps = echoClient.Install(nodes.Get(0));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Run simulation

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Key Components
  1. Node Creation:
    • We generate a node to characterize the routers or endpoints.
  2. RIP Configuration:
    • Utilized their RipHelper to ensure the RIP on nodes.
  3. Traffic Simulation:
    • Utilized the applications such as UDP Echo to create a traffic.
  1. Advanced RIP Configuration

Split Horizon with Poison Reverse

We Enable or disable the split horizon with poison reverse:

ripRouting.Set(“SplitHorizon”, BooleanValue(true));

RIP Version

Set the RIP version (RIP v1 or v2):

ripRouting.Set(“RipVersion”, UintegerValue(2));

Static Routing with RIP

We Combine the static routes through RIP using Ipv4ListRoutingHelper:

Ipv4StaticRoutingHelper staticRouting;

Ipv4ListRoutingHelper listRouting;

listRouting.Add(staticRouting, 10);  // Static routing priority

listRouting.Add(ripRouting, 0);     // RIP priority

  1. Monitoring and Debugging
  1. Enable Logging:

NS_LOG=”RipHelper” ./waf –run rip-example

  1. Inspect Routing Tables: utilized their following and we design the routing tables:

Ptr<Ipv4> ipv4 = nodes.Get(1)->GetObject<Ipv4>();

ipv4->GetRoutingProtocol()->PrintRoutingTable(std::cout);

  1. Capture Traffic: Ensure the PCAP tracing to analyse packet flows in Wireshark:

pointToPoint.EnablePcapAll(“rip-routing”);
