|
|
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:
|
|
type: boolean
|
|
default: True
|
|
description: >
|
|
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.

enable-distributed-floating-ip:

type: boolean
|

default: False
|
|
description: >
|
|
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:
|

type: string

|
|
Geneve VNI IDs that are available for tenant network allocation.

default:
|
|
description: >

type: string

default:
|
|
description: >
|
|
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.
