Hello, During the regression test, I find that Neutron allows CIDR overlapping in same project.
neutron --os-region-name RegionOne net-create dup-net1 neutron --os-region-name RegionOne net-create dup-net2 neutron --os-region-name RegionOne subnet-create dup-net1 20.0.1.0/24 neutron --os-region-name RegionOne subnet-create dup-net2 20.0.1.0/24 all commands can be executed successfully, and after then the project has two subnets with same CIDR: 20.0.1.0/24 Should it be allowed? Or it's just because it's too difficult to address the race condition. Best Regards Chaoyi Huang (joehuang)
