[Rdo-list] instance ips not reusable ?

[Zhao, Xin]

Hello,

I notice that, in my icehouse testbed that runs neutron in OVS/VLAN 
mode, ips from the deleted instances don't seem to be reassigned to new 
instances, new instances always get the next available ip from the range 
incrementally.  I am afraid this will cause problem eventually.  On old 
releases, the ips of the deleted instances get reused pretty quickly on 
new instances. Do I miss some configuration option?

Thanks,
Xin
