Neutron Api Plugin Ovn

dhcp-default-lease-time | int

Default: 43200

Default lease time (in seconds) to use with OVN's native DHCP service.

dns-servers | string

Space-delimited list of DNS servers to use as forwarders if a subnets ``dns_nameservers`` field is empty.

enable-distributed-floating-ip | boolean

This is for specifc use cases only, not generally recommended, see note below. Perform NAT action for floating IPs locally on each chassis. Enabling this requires making external Layer3 connectivity available globally and configuring bridge mappings on all chassis in the deployment. Note: OVN gives you distributed East/West and highly available North/South routing by default. You do not need to enable this option to get that. This is for very specific use cases only. Enabling it will create a scaling problem at the physical network layer that needs to be resolved with globally shared Layer2 (does not scale) or tunneling at the top-of-rack switch layer (adds complexity) and is generally not a recommended configuration.

geneve-vni-ranges | string

Default: 1001:2000

Space-delimited list of <vni_min>:<vni_max> tuples enumerating ranges of Geneve VNI IDs that are available for tenant network allocation.

ovn-dhcp4-global-options | string

Dictionary of global DHCPv4 options which will be automatically set on each subnet upon creation and on all existing subnets when Neutron starts. An empty value for a DHCP option will cause that option to be unset globally. EXAMPLES: - ntp_server:1.2.3.4,wpad:1.2.3.5 - Set ntp_server and wpad - ntp_server:,wpad:1.2.3.5 - Unset ntp_server and set wpad See the ovn-nb(5) man page for available options.

ovn-dhcp6-global-options | string

Dictionary of global DHCPv4 options which will be automatically set on each subnet upon creation and on all existing subnets when Neutron starts. An empty value for a DHCP option will cause that option to be unset globally. EXAMPLES: - ntp_server:1.2.3.4,wpad:1.2.3.5 - Set ntp_server and wpad - ntp_server:,wpad:1.2.3.5 - Unset ntp_server and set wpad See the ovn-nb(5) man page for available options.

ovn-l3-scheduler | string

Default: leastloaded

The OVN L3 Scheduler type to use when scheduling router gateway ports. Available schedulers: - leastloaded - chassis with fewest gateway ports selected (default) - chance - chassis randomly selected

ovn-metadata-enabled | boolean

Default: True

Whether to use the metadata service. Note: The ``ovn-chassis:nova-compute - nova-compute:neutron-plugin`` subordinate relation is a prerequisite for this to work.
