Warninginfo
The segment routing use case is built on an older internal release of ONOS (v0.3.0, and the ). The following instructions do not apply to ONOS 1.0.0 (Avocet), and are meant only for the SPRING-OPEN project.

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.

Edit network configuration file

The following example (sr-3node.conf) shows the network configuration for the topology with three switches and three links (refer to figure below).
