  1. Edit ~/ONOS/conf/onos.properties

    If you create a new network configuration file, you need to specify the file in net.onrc.onos.core.configmanager.NetworkConfigManager.networkConfigFile field. In the example below, conf/sr-3node.conf file was specified.

    onos.properties
    floodlight.modules = net.floodlightcontroller.core.FloodlightProvider,\
    net.floodlightcontroller.threadpool.ThreadPool,\
    net.onrc.onos.core.topology.TopologyPublisher, \
    net.onrc.onos.core.datagrid.HazelcastDatagrid,\
    net.onrc.onos.core.flowprogrammer.FlowProgrammer,\
    net.onrc.onos.core.intent.runtime.PathCalcRuntimeModule,\
    net.onrc.onos.core.intent.runtime.PlanInstallModule,\
    net.onrc.onos.core.registry.ZookeeperRegistry, \
    net.onrc.onos.core.metrics.OnosMetricsModule, \
    net.onrc.onos.apps.websocket.WebSocketModule, \
    net.onrc.onos.core.main.config.DefaultConfiguration, \
    net.onrc.onos.apps.segmentrouting.SegmentRoutingManager
    net.floodlightcontroller.restserver.RestApiServer.port = 8080
    net.floodlightcontroller.core.FloodlightProvider.openflowport = 6633
    net.floodlightcontroller.core.FloodlightProvider.workerthreads = 16
    net.floodlightcontroller.core.FloodlightProvider.cpqdUsePipeline13 = true
    net.floodlightcontroller.forwarding.Forwarding.idletimeout = 5
    net.floodlightcontroller.forwarding.Forwarding.hardtimeout = 0
    net.onrc.onos.apps.websocket.WebSocketModule.port = 8081
    net.floodlightcontroller.core.FloodlightProvider.cpqdUsePipeline13 = true
    # NOTE: Do NOT modify or remove the line below. This value will be overwritten by onos.sh script.
    net.onrc.onos.core.datagrid.HazelcastDatagrid.datagridConfig = 
    # Uncomment and list all the ZooKeeper instances after localhost on multi-instance deployment.
    #net.onrc.onos.core.registry.ZookeeperRegistry.connectionString = localhost:2181,otherhost:2181
    # Specify a network configuration file to be used by the NetworkConfigManager
    net.onrc.onos.core.configmanager.NetworkConfigManager.networkConfigFile = conf/sr-3node.conf
  2. Edit network configuration file

    The following example shows the network configuration for the topology with three switches and three links.

    sr-3node.conf

      "comment": " Segment routing topology description and configuration",
      "restrictSwitches": true,
