Configuration

This step uses the following network:

../../../_images/step31.png
network Network
{
    @display("bgb=1766.2515,641.51587");

    types:
        channel PppLink100M extends DatarateChannel
        {
            delay = 5us;
            datarate = 100Mbps;
        }

    submodules:

        }
        visualizer: IntegratedCanvasVisualizer {
            @display("p=756.675,81.225");
        }
        scenarioManager: ScenarioManager {
            @display("p=1045.2375,81.225");

        }
        R2: Router {
            @display("p=989.6625,356.9625");
        }
        host3: StandardHost {

        host5: StandardHost {

        }
        switch1: EtherSwitch {
            @display("p=320.625,356.9625");
        }
        switch2: EtherSwitch {
            @display("p=1295.325,352.6875");
        }
    connections:
        host2.ethg++ <--> Eth100M <--> switch1.ethg++;
        host1.ethg++ <--> Eth100M <--> switch1.ethg++;
        host0.ethg++ <--> Eth100M <--> switch1.ethg++;
        switch1.ethg++ <--> Eth100M <--> R1.ethg++;

        switch2.ethg++ <--> Eth100M <--> host3.ethg++;
        switch2.ethg++ <--> Eth100M <--> host4.ethg++;
        switch2.ethg++ <--> Eth100M <--> host5.ethg++;

        R1.pppg++ <--> PppLink100M <--> R2.pppg++;
        R2.ethg++ <--> PppLink100M <--> switch2.ethg++;
}

The configuration in omnetpp.ini is the following:

[Config Step3]
description = "OSPF full adjacency establishment and LSDB sync"
network = Network

*.configurator.config = xml("<config> \
                                <interface hosts='R1' names='eth0' address='10.4.5.x' netmask='255.255.255.x'/> \
