Apologies if this is posted to the wrong place, but after talking with Kyle
Mestery (mestery at cisco.com), he suggested that I bring my question here...

I'm trying to make sense of the allow_overlapping_ips configuration
parameter in neutron.

When this entry is true, then a tenant can have subnets with overlapping
IPs in different networks (i.e. the scope of the subnet validation search
is the other subnets associated with the network) which makes sense.

But, when this entry is false, then the validation search appears to cover
all subnets across all tenants.  I'm trying to understand the logic of
this, because I would have expected that in this case, the search scope
would be all subnets across a single tenant.

As it is now, it looks like if an install has this configuration parameter
set to false, then there is no way for that install to reuse the net 10
address space.

Can somebody lend me a hand and either (a) tell me I'm reading the code
wrong or (b) explain why that choice was made?

Thanks in advance,
