In newton external_network_bridge is already set to ''. Really, in the article just need to make sure your bridge mappings are set to both interfaces where each interface represents the external networks.

As far as how that data gets back to one data center rack, really i'ts tunneling, i.e. GRE/VXLAN, in the context of self-service networks.

Subject: [Openstack] Host multiple subnets on one data center rack

I was wondering as to how to host multiple subnets on one data center rack.

Let me explain:

I have a virtual network function, say vRouter.
I have two subnets in the external network 192.168.x.x and 192.178.x.x, then from the edge router how can I get it  to go to different compute nodes..
What is the mechanism in OpenStack to do this? Like a tunnel or something?

How can I achieve the above in my data center with OpenStack?
