restrict floating IP range with a bigger netmask

Asked by li,chen

Hi,

I'm working under Folsom.

I want to create a group of floating IP with 192.168.12.0/24.
This means when I run command "nova floating-ip-create", I hope the IP I get is 192.168.12.xx

But, I also want the netmask for these floating IP is 192.168.0.0/16.
This means I want the instance that is using the floating IP can ping to 192.168.11.xx

Any one know how to do this ?

When creating external subnet with /16, you can specify
--allocation-pool start=192.168.12.0,end=192.168.12.254
