Hi,

can you open a bug report on this and provide your setup configuration? I
just tested this with ML2 and wasn't able to reproduce the issue.

arosen at arosen-MacBookPro:~/devstack$ neutron net-create asdf
 --provider:network_type vlan  --provider:segmentation_id 124
--provider:physical_network  asdf
Unable to create the network. The VLAN 124 on physical network asdf is in
use.

arosen at arosen-MacBookPro:~/devstack$ neutron net-delete asdf
Deleted network: asdf

Thanks,

Aaron
