OpenStack - Split Public API & Floating IP networks
By default in RDO Manager/ RH-OSP, Public API and Floating IP are set in the same subnet.
In some case, it will be useful to split these networks into different subnets and interfaces.
One option is to dedicate a nic for the External network (Public API) and mount a bridge on an other nic for Floating IP:
1. Apply change in YAML controller file:
2. Check the result on controller nodes:
After deployment, you have two specific interfaces on controller nodes:
For this example: eth6 is dedicated for Public API & VIP and br-ex for Floating IPs
3. Create network with neutron
Once interfaces are up and running, the last step is to create network with neutron CLI and bind it on our bridge:
