Hey,

You just a python code and run it with mininet

 sudo mn --mac --controller remote,ip=localhost --switch=ovs --custom ~/topology.py --topo mytopo

The code looks like

from mininet.topo import Topo

class MyTopo( Topo ):
    def __init__( self ):
        # Initialize topology
        Topo.__init__( self )
        # Add hosts
        h1 = self.addHost('h1')
        h2 = self.addHost('h2')
        # Add switches
        s1 = self.addSwitch('s1')
        s2 = self.addSwitch('s2')
        # Add links
        self.addLink(h1,s1)
        self.addLink(h2,s2)
        self.addLink(s1,s2)

topos = { 'mytopo': ( lambda: MyTopo() )}

Thank you for the reply, and sharing this script with me, I already made a mininet topology, i followed the tutorial provided by onos (which has the clustered onos instances in the vm and the spine topology) i managed the intents.
I wanted something more advanced than this to learn onos, but i didn't find it.

What advanced level do you mean?

You should think of an application to create and after that, you figure out how to create it.
