sudo mn --controller=remote,ip=<Controller IP> --topo=linear,3 --switch ovsk,protocols=OpenFlow13 sudo mn --controller=remote,ip=127.0.0.1 --topo=linear,3 --switch ovsk,protocols=OpenFlow13
The above command will create a virtual network consisting of 3 switches. Each switch will connect to the controller located at the specified IP, i.e. 127.0.0.1
sudo mn --controller=remote,ip=127.0.0.1 --mac --topo=linear,3 --switch ovsk,protocols=OpenFlow13
The above command has the "mac" option, which makes it easier to distinguish between Host MAC addresses and Switch MAC addresses.
