Description

My customer is building a new SW-defined data center using IPv6 only. IPv6-only is mandatory for compliance with the IPv6 Master Plan for the German federal public administrations, as well as various EU regulations. This includes all management networks and tools.

Beginning with release 3.0(1), Nexus Dashboard supports pure IPv6 configurations for the cluster nodes and services. However in the current version of the nd_setup module, various IPv4 parameters are required. For IPv6-only support, IPv4 and IPv6 parameters need to become choices instead. For example, ipv4_address/ipv4_gateway only, ipv6_address/ipv6_gateway only, or both. Similar, app_network/service_network and app_network_ipv6/service_network_ipv6.
