Creating an external floating IP Neutron network
In Neutron, it is easy to create many private networks that allow communication between your instances. To allow access from your client to these, though, we must create a router on the provider network (an external network) that is routed into our OpenStack environment. This provider network allows us to allocate floating addresses to our instances.

If you created this node with Vagrant, you can execute the following command:
