[openstack-dev] [neutron] multiple external networks on the same host NIC

As an operator, is there a way I can create two external networks from
Neutron's point of view, where both of those networks are accessed through
the same host NIC? Obviously those networks would be using different
subnets. I need this sort of thing because the two subnets are treated
differently by the stuff outside of OpenStack, so I need a way that a
tenant can get a floating IP of the sort he wants. Since Neutron equates
floating IP allocation pools with external networks, I need two external
I asked this on openstack-operators, and got one response saying my
choices are either to use VLAN tagging on that NIC or manually make more
OVS switches that ultimately get their external connectivity through the
same NIC. The VLAN tagging is problematic in my environment. Is there
any other choice?
BTW, I am currently using Juno but plan to move to Kilo.
BTW, is Neutron creating any ebtables rules that will get in my way?
