[ovs-discuss] about spanning tree

[Steven Lee]

Hi,
    I created a br0 and enabled stp to prevent loop with following commands:

ovs-vsctl add-br br0
ovs-vsctl set bridge br0 stp_enable=true
ovs-vsctl add-port br0 eth0
ovs-vsctl add-port br0 eth1

since eth0 and eth1 are connected by physical switches, the port eth1 is
blocked.
I'm wondering does it always block one of the port of openvswitch?

   For example: if eth0 is connected to a physical switch A.
                          eth1 is connected to a physical switch B.
                          and physical switch A and B are also connected.
   does it always block one of the port on openvswitch? or is it possible
that it would blocked the    connection between A and B?

Thanks,


Steven Lee
