Hi Alexey,
I'm running a script as below on each VMs to create the virtual topologies.from
mininet.topo import Topo
from mininet.net import Mininet
from mininet.log import setLogLevel
from mininet.cli import CLI
from mininet.node import RemoteController
from functools import partial
from mininet.node import OVSSwitch
class Approach2Topo(Topo):
def __init__(self, cpu=.1, max_queue_size=None, **params):
# Initialize topo
Topo.__init__(self, **params)
# Hosts and switches
s1 = self.addSwitch('s1')
h1 = self.addHost('h1')
h2 = self.addHost('h2')
# Wire h1 and h2 to s1
self.addLink(h1, s1)
self.addLink(h2, s1)
def setup():
topo = Approach2Topo()
# We use Open vSwitch and OpenFlow 1.3
switch = partial(OVSSwitch, protocols='OpenFlow13', datapath='user')
#controller
net = Mininet(topo, controller=RemoteController,
switch=switch, cleanup=True)
# Setting up hosts
net['h1'].setIP('10.0.1.1/24')
net['h1'].setMAC('00:00:00:00:01:01')
net['h1'].cmd('route add default gw 10.0.1.100')
net['h2'].setIP('10.0.1.2/24')
net['h2'].setMAC('00:00:00:00:01:02')
net['h2'].cmd('route add default gw 10.0.1.100')
# Setting up routers
net['s1'].cmd('ifconfig s1-eth3 hw ether 00:00:00:11:11:11')
net.start()
CLI(net)
net.stopThanksHadem

what are h1,2,3,4? those are hosts or guests (VMs)? What are r1,r2?You have
two VMs on separate hosts? (1 guest on each host?)
Bridging guests on hosts Etherenet port will work, if the hosts are connected.

Hi Oliver,
I have the following scenario/network environment on the same physical system.
VM1: VM2:h1 ------------r1
r2-------------h3 | |
h2 h4
I want to ping h3 from h1. The above virtual topologies are created using
custom Mininet/Python scripts. I have also set up internal interfaces on both
the VMs.However ping is not working from h1 to h3.Pls advice how to get the
ping/connectivity working.

If both your VM are created on the same physical system, there should
not be any reason that prevent it.
If the VM are created on different physical systems, it depends how your
network is configured: bridged, yes, NATed, no.
Best regards,
Olivier
