How to set a subnet as the default ip allocation net?

I have a network called "external" which has two subnets "external-public" and "external-share". Here are the subnets information:

  • external-public: | start ip:, end ip:
  • external-share : | start ip:, end ip:

I want to configure the machines (instances, routers, floating IPs etc.) to allocate the IPs in the external-share instead of external-public . However, it always allocate an IP in the external-public for me.

I can allocate an IP with a specific subnet via the OpenStack CLI client. But I wonder that is there a way to do this via horizon dashboard ? Or is there any way to set the subnet become the network "default" subnet ?

If your using dashboard, unless external-public subnet's IP allocation is full, it will not allow allocating IP from external-share
