Public bug reported: With the current Neutron implementation, a subnet cannot be deleted until all associated IP addresses have been removed from ports (via port update) or the associated ports/VMs have been deleted.
In the case of SLAAC-enabled subnets, however, it's not feasible to require removal of SLAAC-generated addresses individually from each associated port before deleting a subnet because of the multicast nature of RA messages. For SLAAC-enabled subnets, the processing of subnet delete requests needs to be changed so that these subnets will be allowed to be deleted, and all ports get disassociated from their corresponding SLAAC IP address, when there are ports existing on the SLAAC subnet. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
