I am in the process of setting up RDO

Is there a reference architecture set up for a server with 2 NICs? eth0 + eth1

eth0 == External network (1 public IP) eth1 == Internal network for API calls etc (10.1.1.x)

Appreciate assistance

if you want to setup openstack then you need the following networks:-

  1. Management network - internal API calls, internal communication of services via AMQP server and also Datbase qeuries.

  2. Data Network- For traffic between VM's and Network node.

  3. Public Netwok- External network which will be used to access VM's from outside (external world)

Ideally for each network it is recommend to have separate Interfaces so 3 NIC's are used but as you mentioned you have 2 NIC's there in this case you Data and Management network will be clubbed on the same interface. It is possible and there are no errors encountered but the only thing is its only good for PoC or testing kind of things and not good for Production Setups

I have only 2 NICs. Do you have a sample of how your eth0 and eth1 looks like? As well as br-ex and br-eth1 ?

See this image ... Here the data Network(blue line) and Management Network(Red Line) are separate, in your case it would be same ... Configuration wise it depends upon which net topology you are using ..Can you please tell me that
