Hi Xabier,

Nowadays I'm also working on the same approach as you: Layer 2 Bridges!

Looking to your 'server p4lang p4' you also need to export the 'interface 
bvi1' that is related to your 'bridge 1', for example: export-port bvi1 700 
10 0 0 0

You said that the interfaces are down so probably this is not your main 
problem but I you will need to export it.

Best regards,
Carmen Misa
