It seems that your issue is not that the traffic isn’t getting to the other side – but rather that you aren’t popping the MPLS label, right?
Can you provide the rules that you entered (the add-flow command) rather than dumping the flows?

The version of ovs is 2.0.1, but I did run the most recent version from git with similar results. Any help here would be appreciated.
