Hi,

I have to connect two buildings with hi speed and reliable link.

I use 2 couple of SXT G-5HPacD and 2 RB2011iL-IN.

Each couple of SXT is bridging eth and Wireless interface as described in this document:
http://wiki.mikrotik.com/wiki/Bridging_ ... s_with_SXT

On each RB2011 I've bondend the two eth interfaces where SXT are connected with 802.3ad.

Now all seem to work but traffic is concentrated only on eth4.
If I disconnect eth4 link doesn't work.
Reconnect eth4, no comunication.
Disconnect eth5 connection return to work.
Reconnect eth5 all traffic on eth4.

I've tested single couple of SXT with direct attached computer and seem to work: I can ping to computer to the other side.

Have anyone idea or other tests to troubleshot this configuration?

Thanks
