Hello,
The OpenFlow 1.3 plugin does not discover the topology with mininet 2.0 on Ubuntu precise. How to reproduce:

and run it with ./run.sh -of13

Install Ubuntu Precise 64 Bit. And issue the following commands:

apt-get install mininet
service openvswitch-switch start
cat > mininet_sample_topo.py <<EOF
from mininet.topo import Topo

class SampleTopo( Topo ):
"Simple topology"

def _init_( self ):
"Create custom topo."

Switches
s1= self.addSwitch( 's1' )
s2= self.addSwitch( 's2' )
s3= self.addSwitch( 's3' )
s4= self.addSwitch( 's4' )

self.addLink( h3, s2 )
self.addLink( h4, s2 )

self.addLink( h5, s3 )
self.addLink( h6, s3 )

self.addLink( s1, s2 )
self.addLink( s1, s3 )
self.addLink( s2, s4 )

self.addLink( s4, h7 )
self.addLink( s4, h8 )
self.addLink( s4, h9 )

topos =

{ 'sampletopo': ( lambda: SampleTopo() ) }

EOF

(ubuntu) [/root] mn --custom mininet_sample_topo.py --mac --topo sampletopo --switch ovsk,protocols=OpenFlow13 --controller remote,ip=<ip>

Find the log file attached.
