I learned that this use case is kind of Hierarchical scenario:
https://specs.openstack.org/openstack/neutron-specs/specs/kilo/ml2-hierarchical-port-binding.html

In such scenario, user wants to use OVN to manage vlan networks, and the
vlan networks is connected via VTEP overlay, which is not managed by OVN
itself. VTEP is needed to connect to BM/SRIOV VMs to the same L2 that OVS
VIFs are connected to.

User don't want to use OVN to manage VTEPs since there will be flooding to
many VTEPs. (Mac-learning is not supported yet)

So in this scenario, user want to utilize distributed logical router as a
way to optimize the datapath. For VM to VM traffic between different vlans,
instead of going to a centralized external L3 router, user wants the
traffic to be tagged to the destination vlan directly and go straight from
source HV to destination HV through the destination vlan.

In the vtep scenario, this is a valuable optimization. Even in a normal
vlan setup without vtep, this can be an optimization too if src and dst VMs
are on the same HV (so that the packet doesn't need to go to physical
switch and come back).

So, I agree with Qianyu that connecting VLAN networks with logical router
is reasonable, which means, the transport of logical router can be not only
tunnels, but also physical networks (localnet port). To fulfill this
requirement, we need to solve some problems in current OVN code:

1) Since the data path is asymmetric, we need to solve the CT problem of
the localnet port. I agree with the idea of the patch from Qianyu, which
bypasses FW for localnet ports, since localnet port is to connect real
endpoints, so maybe there is not much value to add ACL on localnet ports.
Not sure if there is use case where ACL is really needed for localnet ports.

2) When there are ARP requests from vlan network (e.g. from a BM) to
logical router interface IP, the ARP request will reach every HV through
the localnet port and the distributed logical router port will respond from
every HV. Shall we disable ARP response from logical router for requests
from localnet port? In this scenario, I would expect the BM/SRIOV VMs on
the same vlan to use a different GW rather than the logical router.

3) We need to add a restriction/validation so that the localnet connection
is used only we are sure the 2 logical switches are on the same "physical
network", e.g. different vlans under same physical bridge group, or a
virtual L2 bridge group formed by vtep overlays.

Thanks,
Han
