Hopefully you've already done the ONOS tutorial, so you already have the ONOS tutorial VM available. If not, check out the Setup your environment <LINK> section of the ONOS tutorial to get the VM ready.

Starting the tutorial

When you start the VM, you'll be presented with a login screen. (If you're already logged in to another tutorial, please log out by clicking the bottom-left icon, clicking "Logout", then click "Logout" again).

Each tutorial in the VM is presented as a different user. Log in to the SDN-IP tutorial user with the following credentials:

Username: sdnip
Password: sdnip

You'll be deposited on a desktop with a bunch of icons that will be used for the tutorial. Before we get started, double-click on the "Reset" icon. This will pop up a terminal and reset ONOS to make sure there is no state left over from any other tutorials.

The network topology

We've prepared a simple emulated Mininet topology, which contains some OpenFlow switches to make up the SDN network. Connected around the edges of the SDN network are emulated routers. The routers run a piece of software called Quagga, which is an open-source routing suite. Note that it is not mandatory to use Quagga; any software/hardware capable of speaking BGP will do. In our case we run the BGP part of Quagga on them, to simulate external BGP routers belonging to other administrative domains. The goal of SDN-IP is to be able to talk BGP with these routers in order to exchange traffic between the different external ASes.
