1/ other missing point in the conf, I suppose I also have to add "export-vrf "
2/ thank you Csaba, is it easy to have the bridging available in the p4lab ?
if not I will then implement it elsewhere ...

Regards
Xavier

and i see an other issue: the p4lab profile does not have bridging enabled in
tofino.bin....

Xavier,

You exported sdn1.2200 with id: 133 which is TOFINO port 31/1 on WEDGE
(At least on WEDGE in my LAB)

Sub-interface or logical interface should not use port_id used by TOFINO.

In my example I put:
export-port sdn1.2200 211 10 0 0 0

You are safe to use ID _above_ 200.

So for sdn3.2200 you can declare it as:
export-port sdn3.2200 212 10 0 0 0

But remove these lines:
export-port sdn2.2200 141 10 0 0 0

141 is TOFINO port 32/1 ...

sdn3.2200 declaration is OK
export-port sdn3.2200 202 10 0 0 0

Hello

thank you

I added the bridge (export-bridge) and the 2 interfaces (export-port)
I also put nothing in sdn1 (previously there was IP addresses)
but still the interface sdn1 and sdn1.2200 are down

AMS0001#show running-config interface sdn1
interface sdn1

You can look at freertr test case here:
http://sources.nop.hu/cfg/p4lang-acl13.tst

You ll be able to see how bridge and related interface are declared.

You also have to add the bridge in "server p4lang p4 If you want it to be
taken into account by the dataplane.

AMS0001(cfg)#server p4lang p4
AMS0001(cfg-server)#export-bridge ?
<num> - bridge number


And also the interface you bound to the bridge. e.g sdn1.2200

AMS0001(cfg-server)#export-port sdn1.2200 211 10 0 0 0

We declare a bridge and put a subinterface sdn1.2200 in the bridge
