Step 9. Measure RIP recovery time¶

Goals¶

TODO

The model¶

This step uses the same network as the previous one.

The configuration in omnetpp.ini is the following:

[Config Step9]
description = "Measure RIP recovery time"
extends = Step2
sim-time-limit = 1500s

*.host0.numApps = 1
*.host0.app[0].typename = "UdpBasicApp"
*.host0.app[0].destAddresses = "host6"
*.host0.app[0].destPort = 1234
#*.host0.app[0].startTime = 50s
*.host0.app[0].sendInterval = 0.5s
*.host0.app[0].messageLength = 32 bytes

*.host6.numApps = 1
*.host6.app[0].typename = "UdpSink"
*.host6.app[0].localPort = 1234

# TODO: change startup time to maximise the effect of triggered update
*.router*.rip.startupTime = uniform(0s,1s)
# enable split horizon in order for the scenario to work properly
*.router*.rip.ripConfig = xml("<config> <interface hosts='router*' mode='SplitHorizon' /> </config>")

#*.scenarioManager.script = xmldoc("scenario3.xml")

*.scenarioManager.script = xmldoc("scenario7.xml")
# break link between router2 and switch1; with scenario3, the link doesn't recover

*.router*.rip.triggeredUpdate = ${triggeredUpdate = false, true}

The scenario manager script:

<!-- scenario7.xml -->
<scenario>
    <at t="50">
        <disconnect src-module="router2" dest-module="switch1" />
    </at>
    <at t="602">
        <connect src-module="router2" src-gate="ethg$o[0]" dest-module="switch1" dest-gate="ethg$i[3]" channel-type="inet.node.ethernet.Eth10M" />
        <connect src-module="switch1" src-gate="ethg$o[3]" dest-module="router2" dest-gate="ethg$i[0]" channel-type="inet.node.ethernet.Eth10M" />
    </at>
</scenario>

No Netmask Routes:

[Config Step9NoNetmaskRoutes]
extends = Step9

**.netmaskRoutes = ""
*.configurator.addDirectRoutes = true
