The Network that is designed through the Network Designer can be started from the UI or started from the command line after creating the configuration file in the Network Designer tool. The Network Simulator provides the facility to dynamically configure IP addresses when starting each agent instance in the network. This facility is supported in Windows NT, 2000, XP and Linux/Solaris OS, when the system is started with Admin user access. Refer to Configuring Virtual IP Address, for more information.
