1) If you declared an additional VRF you’d indeed have to export it in 
"server p4lang p4 »
2) You need to recompile p4 program with HAVE_BRIDGE, or load a compile 
version having BRIDGE via GRPC

This is why I suggest you should start first with model :)

That being said, I just finished counters implementation on our internal LAB.

So you an use it in order to validate bridge L2 features.

I can compile this profile for you:
