The model is that, I need two bridge "inline", 1 do send the packet from DTN1 
to Stordis1, and the other from Stordis2 to DTN2. And if this bridge domains 
are mac aware, it can make some confusions, since DTN1 mac will be received 
twice, first comming from DTN1 and after comming from Stordis2.
Using QinQ normally, you are not mac-aware of the cliente-VLAN, so it solves 
the problem.
Using some L2 Cross-connects can also help.

I'm testing using 2 bridges, but it is intermmitent, I´ll post the config and 
results soon after some additional tests.

Regards,

Marcos Schwarz

connections between different ports

hi,

so this means that the qinq would be addressed transparently and it will 
work. Right?
