[openstack][neutron]Cannot schedule router to specified AZ

Hello.

I am planning to separate network AZ looks like:

2 network nodes for AZ1 2 network nodes for AZ2

I can select AZ when creating a router from AZ hints but It wont work as I expect.

Router should only schedule on my selected AZ.

Could you correct me if I am wrong.

Thank you.
