Manuel/Babu, I didnt see your emails on the OPNFV SFC lists. The OPNFV Tech Discuss list has way too many emails to keep up with. In the future, can you please put "[SFC]" in the subject so that your emails go to the OPNFV SFC list.
For starters, your statement about reg0=0x1 is based on using ODL Boron, and this will change in ODL Carbon. I mention this, because in Carbon it will be easier for the classifier to direct what to do with the packets at chain egress, like egressing them out of Openstack. It is indeed a very valid use case for traffic to originate from outside of Openstack. Likewise for traffic destined to the internet, also a very valid use case. Probably the main reason we dont have anything setup for that now is for simplicity in our test cases, but its about time we look into doing this. Integrating L3VPN with SFC would certainly simplify this, but we should investigate how to do this without it.

I think that the use case cannot be implemented with ODL Boron becase of two problems: 1 - Right now only traffic which comes from local VMs where the classifier is implemented is classified. The key here is the match parameter reg0=0x1 which is only added to that local traffic. Because of this, we cannot classify traffic coming from outside of OpenStack towards a server VM. 2 - Imagine the traffic destination is not a server VM in openstack and that traffic is just forced to go to openstack. It accesses SFC and then must come back to the original destination, as far as I know, we have no way to redirect the traffic to a destination which is outside of openstack, right? Until the interation with L3VPN is not done, I don't know how this could be done. Do you agree or am I missing anything? Is any of these problems going to be solved with ODL Carbon?
