Hello! We use OVN Geneve networks with the VTEP-gateway mechanism. It is part of our OpenStack installation.
OVN returns max_tunid=4095 to OpenStack ML2 driver because of VXLAN and Geneve are enabled in OVN But the real max_tunid in case using VXLAN only for VTEP-gateway is 16 million (all 24 bits). It is impossible to disable VXLAN in OVN, because it is required by the VTEP-gateway mechanism. So my question is which way is the best for our case, just ignore max_tunid in OpenStack-ML2 driver? Or maybe add a patch for OVN for returning the correct max_tunid in case of using VXLAN only for the VTEP-Gateway mechanism?
