Hi IPv6 experts, This is regarding the BP - https://blueprints.launchpad.net/neutron/+spec/ipv6-two-attributes Is it possible to give me a quick example of the CLI that you envision? This is so that the Horizon BP can be updated accordingly. Once the neutron side of things is ready, when creating a subnet, and the version is IPv6 will now enable these two options, yes? Can both options exist or is it an either/or combination, i.e. either ipv6_ra or ipv6_address? Thanks!
