While I can create Flat external network, I can't create that with vxlan type with same command (just changed flat to vxlan):

openstack network create --provider-physical-network extnet --provider-network-type vxlan public --external

The error says "invalid input for operation: provider:physical_network specified for vxlan network".

I believe provider-physical-network is only compatible with Flat or VLAN, though I currently don't see where this is documented.

The code that generates the error refuses any tunnel-type network (GRE, VXLAN, Geneve) that has this option.

when I create external network in Horizon, it will use vxlan type but do not connect that to physical network, that is why I used cli openstack client.

If you mean Packstackwhen you say RDO, you need to know that Packstack’s “external” network is by default isolated and not connected to your real external network. To change this, see
