[Learn about configurations >](https://juju.is/docs/juju/configuration#heading--application-configuration)

* debug | boolean

  Enable debug logging.
* dns-domain | string

  Default: cloud.sunbeam.internal.

  Specifies the dns domain name that should be used for building instance
  hostnames. The value of 'openstacklocal' will cause
  the dhcp agents to broadcast the default domain of openstacklocal and
  will not enable internal cloud dns resolution. This value should end
  with a '.', e.g. 'cloud.example.org.'.
* dns-servers | string

  Comma separated list of DNS servers to use as forwarders if subnet's
  dns\_nameservers is not set. If not set, DNS resolvers of the host
  running neutron server will be used.
* enable-distributed-floating-ip | boolean

  Enable or disable distributed floating IP functionality in OVN.
  When enabled, floating IPs are managed by distributed routers.
* enable-igmp-snooping | boolean

  Enable IGMP snooping for integration bridge.
* global-physnet-mtu | int

  Default: 1500

  MTU of the underlying physical network. Neutron uses this value to
  calculate MTU for all virtual network components. For flat and
  VLAN networks, neutron uses this value without modification. For
  overlay networks such as Geneve, neutron automatically subtracts
  the overlay protocol overhead from this value.
* ipv4-ptr-zone-prefix-size | int

  Default: 24

  The size in bits of the prefix for the IPv4 reverse lookup (PTR) zones.
  Valid size has to be multiple of 8, with maximum value of 24 and minimum
  value of 8.
  .
  NOTE: Use only when "reverse-dns-lookup" option is set to "True".
* ipv6-ptr-zone-prefix-size | int

  Default: 64

  The size in bits of the prefix for the IPv6 reverse lookup (PTR) zones.
  Valid size has to be multiple of 4, with maximum value of 124 and minimum
  value of 4.
  .
  NOTE: Use only when "reverse-dns-lookup" option is set to "True".
* path-mtu | int

  Default: 1500

  Maximum size of an IP packet (MTU) that can traverse the
  underlying physical network infrastructure without fragmentation
  when using an overlay/tunnel protocol. This option allows
  specifying a physical network MTU value that differs from the
  default global-physnet-mtu value.
* physical-network-mtus | string

  Space-delimited list of <physical\_network>:<mtu> pairs specifying MTU for
  individual physical networks.
  .
  Use this if a subset of your flat or VLAN provider networks have a MTU
  that differ with what is set in global-physnet-mtu.
* region | string

  Default: RegionOne

  Name of the OpenStack region
* reverse-dns-lookup | boolean

  A boolean value specifying whether to enable or not the creation of
  reverse lookup (PTR) records.
  .
  NOTE: Use only when integrating neutron-k8s charm to designate charm.
* vlan-ranges | string

  Default: physnet1:1:4094

  Space-delimited list of <physical\_network>:<vlan\_min>:<vlan\_max> or
  <physical\_network> specifying physical\_network names usable for VLAN
  provider and tenant networks, as well as ranges of VLAN tags on each
  available for allocation to tenant networks.
