Is VLAN provider networks the right solution?

Still learning as I go, but am not satisfied with the floating IP being NAT, would prefer non-routable IP space and public IP space to be on separate interfaces within an instance.

My current setup has controller, network, 2x compute, block and object storage all on separate hosts, all hosts have 2 1Gbit NIC and 2 10Gbit NIC, currently networking is OS Networking(neutron) as outlined in the Juno install docs for Ubuntu 14.04

From the searching and reading it seems VLAN provider networks are the solution, but am not seeing any examples I've been able to wrap my head around. My worry is breaking what I currently have working.

VXLAN as well as GRE tunneling eliminates a lot of headaches connected with VLAN network provider.

Devstack been run on Ubuntu 14.04 also creates both public and private networks of VXLAN type.

thanks dbaxps, but my question is really do I get an interface with the external network and another interface for internal traffic? Some applications are license based on the public IP so the instance needs to be exposed to function properly.

It's a bit confusing. You are concerned would Neutron router provide you properly working gateway to external network along with properly working interface to L2 layer tenant's network. Am I correct ?

I've also checked http://docs.openstack.org/juno/instal... and discovered recomendations for /etc/neutron/plugins/ml2/ml2_conf.ini on Network && Controller Nodes. They recommend GRE tunneling for Juno.

In regards of RDO Juno on CentOS 7 and F21 VXLAN provider networks is a standard solution. Compute nodes are connected via VXLAN tunnels to Network Node ( so tenants networks all are of VXLAN type). When I create external network it usually belongs admin tenant is shared and also has VXLAN type.
