Invoking Ryu

Invoking Ryu

The following command starts Ryu.

ryu-manager

But ryu-manager itself doesn't provide useful functionalities by default. ryu-manager provides an environment to run Ryu applications, which provide functionalities which you likely want. The following command starts ryu-manager and makes it load a Ryu application 'simple_switch', which implements L2 learning switch functionality.

ryu-manager ryu/app/simple_switch.py

You can load any number of Ryu applications simultaneously. (Note that this is not a magic. To use multiple Ryu applications safely, they need to be written to coordinate.)

ryu-manager ryu/app/simple_switch.py ryu/app/rest.py

If you are interested in other options, try:

ryu-manager --help
