Description

OSM creates an IPv6 network and subnet with default values, in production, is needed to consider additional parameters like ipv6_address_mode and ipv6_ra_mode, the command for this in OpenStack is like this:

openstack subnet create --network ipv6_net --ipv6-ra-mode dhcpv6-stateful --ipv6-address-mode dhcpv6-stateful --subnet-range 2001:DB8::/64 --gateway 2001:DB8::1 --allocation-pool start=2001:DB8::2,end=2001:DB8::8 --dhcp --ip-version 6 ipv6_subnet

Demo or definition of done

IPv6 should be created with specific ipv6_address_mode and ipv6_ra_mode parameters
