John, yes. Some sort of header. We are currently using a mpls tag. The idea is to translate it to a geneve header within the purview of ovn confines and possibly map to a vxlan vni across l2 tunnel. All options are prevalent now, nothing new. Based on my info, mpls tags can be inferred from within ovs and could be used in match. If not we are building that also. The next question is how do we map from your case of bump on wire service unaware - well, that is why we have a number of classifiers around or if I can use connection tracker or some other means to keep track in a short span say within a single switch. Will deal with them as we go.
