[Bug 1372441] Re: [RFE] Creating port in dual-stack network requires IPv4 and IPv6 addresses to be allocated

 

The consensus is that Neutron has enough existing primitives to address
user's expectations when dealing with dualstack environments.

The situation that prompted this RFE where address exhaustion on one
subnet may lead to a user facing error may be prevented by being
explicit on what subnet to allocate from. This is inline with comment
#13, therefore there's really no more room for confusion.

Title:
  [RFE] Creating port in dual-stack network requires IPv4 and IPv6
  addresses to be allocated

Status in neutron:
  Won't Fix

Bug description:
  Currently, when creating port in dual-stack network (network with one
  ore more IPv4 subnets and one or more IPv6 subnets), Neutron allocates
  fixed-ip from both, v4 and v6 subnets.  If one of the subnets do not
  have available addresses, it is considered as error.

  IMO, this is wrong.  Operation should succeed if at least one address
  (IPv4 of IPv6) was allocated.
