Hello,
I am trying to create a custom topology, which is something like this
s1 --------- s2
l l l l
h1 h2 h3 h4
I am connecting this custom topology to a remote controller, here Ryu
controller in consideration.
The python script written to create this topo is given below.
*#!/usr/bin/python*
*from mininet.net <http://mininet.net/> import Mininet*
*from mininet.node import Controller, RemoteController*
*from mininet.cli import CLI*
*from mininet.log import setLogLevel, info*
*def customNet():*
* net = Mininet(controller=RemoteController)*
* c1 = net.addController('c1', controller=RemoteController,
ip="192.168.56.101", port=6633)*
* h1 = net.addHost( 'h1', ip='10.0.0.1' )*
* h2 = net.addHost( 'h2', ip='10.0.0.2' )*
* h3 = net.addHost( 'h3', ip='10.0.0.3' )*
* h4 = net.addHost( 'h4', ip='10.0.0.4' )*
* s1 = net.addSwitch( 's1' )*
* s2 = net.addSwitch( 's2' )*
* s1.linkTo( h1 )*
* s1.linkTo( h2 )*
* s2.linkTo( h3 )*
* s2.linkTo( h4 )*
* s1.linkTo( s2 )*
* net.build()*
* c1.start()*
* s1.start([c1])*
* s2.start([c1])*
* CLI( net )*
* net.stop()*
*if __name__ == '__main__':*
* setLogLevel( 'info' )*
* customNet()*
My main concern is that I want to use OfSoftSwitch13 in this custom
topology instead of OVS, so while executing this I used
*sudo mn --switch user,protocols=OpenFlow13 --controller
remote,ip=192.168.56.101 --custom customNet.py*
But this leads to the creation of a bsic topology like this

Please help me know the reason for this. And what should I do to have
OfSoftswitch13 instead of OVS. What am I doing wrong in this?
