[ovs-discuss] Cannot forward bpdu through openvswitch

Dear all,

I am using OVS 2.1.2

I want to configure a switch with two ports to transparently forward
what comes to one port to the other. These are the rules that I am
using:

 cookie=0x0, duration=77674.340s, table=0, n_packets=0, n_bytes=0,
idle_age=65534, hard_age=65534, in_port=1 actions=output:2

 cookie=0x0, duration=77674.336s, table=0, n_packets=38713,
n_bytes=2013076, idle_age=0, hard_age=65534, in_port=2
actions=output:1

On on side of this OVS I have a bridge using STP and generating STP
BPDUs, I would like to have OVS forward them to the other side (as it
should looking at the rules), but OVS seems to be dropping the BPDUs.

I have found you can configure "other-config:forward-bpdu=true" but it
is not working for me. What version do I need to make us of
forward-bpdu? Is there a way to make a 2.1.2 OVS forward STP bpdus?

Thanks

Daniel
