Hello all

Would you plz help. I am very new in mininet

I have this topology in mininet. However, when I add some flows in flow
table the host h1 and h2 cannot ping each other, though there is no error
when adding dpctl add-flow.

Can anyone help please????

sudo mn --topo=linear,3 --mac --switch ovsk --controller=remote

mininet> net
