hi all,
im new with openvswitch, i have three node openvswitch, in each switch i
create gre
tunnel to other switch, i also add stp_enable=true in every switch.
but i have some problem, every host that connected to switch 1 can ping to
switch 2(vice versa) but host in switch 3 can ping to host connected to
switch 1 and 2(vice versa). do you guys any suggestion why that is happen?
