Description of IPv6 configuration options
Configuration option = Default value Description
[DEFAULT]

fixed_range_v6 = fd00::/48

(String) This option determines the fixed IPv6 address block when creating a network.

Please note that this option is only used when using nova-network instead of Neutron in your deployment.

Possible values:

Any valid IPv6 CIDR. The default value is "fd00::/48".

Related options:

use_neutron

gateway_v6 = None

(String) This is the default IPv6 gateway. It is used only in the testing suite.

Please note that this option is only used when using nova-network instead of Neutron in your deployment.

Possible values:

Any valid IP address.

Related options:

use_neutron, gateway

ipv6_backend = rfc2462

(String) Abstracts out IPv6 address generation to pluggable backends.

nova-network can be put into dual-stack mode, so that it uses both IPv4 and IPv6 addresses. In dual-stack mode, by default, instances acquire IPv6 global unicast addresses with the help of stateless address auto-configuration mechanism.

Related options:

  • use_neutron: this option only works with nova-network.
  • use_ipv6: this option only works if ipv6 is enabled for nova-network.

use_ipv6 = False

(Boolean) Assign IPv6 and IPv4 addresses when creating instances.

  • use_neutron: this only works with nova-network.
