The patch introduces a new config section ovn_nb_global. All options from this section are passed to OVN Northbound NB_Global table to configure Northbound OVN. First option is ignore_lsp_down to override OVN default configuration. This option was changed in OVN to `true` [1] but for Neutron it's better to not answer ARP packets when ports are in DOWN status.

upgrade:
|
|
- |
|
|
Starting with OVN version v21.12.0, OVN replies to ARP requests for ports
|
|
that are in a DOWN status. It does not reply in versions older than
|
|
v21.12.0. In order to keep the same behavior in Neutron, the default OVN
|
|
behavior is overridden by Neutron and Neutron ports will no longer reply to
|
|
ARP packets if the ports are in a DOWN state. If it is required to reply to
|
|
ARP for such ports, the config option ``ignore_lsp_down`` from
|
|
``[ovn_nb_global]`` section can be set to True in the Neutron config. It is
|
|
set to False by default.
