Description Kamil Sambor 2019-10-30 10:10:28 UTC

For distributed vlan in ovn we need to add support of creating mac addresses per compute and seting them in external_ids:ovn-chassis-mac-mappings .

In case when we have NeutronBridgeMappings='datacentre:br-ex' then for every compute node we need to generate mac and addset it in ovn_controller to external_ids:ovn-chassis-mac-mappings: 'datacentre:generated_mac' [0]

Comment 2 Daniel Alvarez Sanchez 2020-04-30 15:37:25 UTC

As mentioned in the BZ description, to achieve this we require to populate local OVSDBs with 'external_ids:ovn-chassis-mac-mappings'.

But also from Neutron, we need to remove the 'reside-on-redirect' option from the LRPs, basically partially reverting this:

Comment 17 Andrew Austin 2021-09-14 17:39:52 UTC

Using the 16.2 RC which seems to contain these patches, external_ids:ovn-chassis-mac-mappings is not populated without patching some stuff in THT and the Ansible roles.

Ansible (Changed output JSON file to be properly formatted for hiera):

(osp1) [stack@osp1-director tripleo-hieradata]$ cat templates/ovn_chassis_mac_map.j2 

{% set ovn_chassis_mac_map_data = {} %}
{% set _ = ovn_chassis_mac_map_data.__setitem__('ovn_chassis_mac_map', hostvars[inventory_hostname].get('ovn_chassis_mac_map', {})) %}
{# RENDER #}
{{ ovn_chassis_mac_map_data | to_nice_json }}


THT (Added ovn_chassis_mac_map to hieradata_files):

(osp1) [stack@osp1-director openstack-tripleo-heat-templates]$ grep -C 20 ovn_chassis overcloud.j2.yaml 
            - {get_param: {{role.deprecated_param_extraconfig}}}
{%- endif %}
            - {get_param: {{role.name}}ExtraConfig}
        extraconfig: {get_param: ExtraConfig}
        hieradata_files:
          - '%{::uuid}'
          - fqdn
          - docker_puppet # Optionally provided by container-puppet.py
          - ansible_managed
          - heat_config_%{::deploy_config_name}
          - config_step
          - role_extraconfig
          - extraconfig

          - ovn_chassis_mac_map # provided by tripleo-hieradata
          - net_ip_map
          - '%{::osfamily}'
          # The following are required for compatibility with the Controller role
          # where some vendor integrations added hieradata via ExtraConfigPre
          - neutron_bigswitch_data # Optionally provided by Controller/ComputeExtraConfigPre
          # Special variable for upgrade
          - upgrade

We need https://review.opendev.org/c/openstack/python-tripleoclient/+/847194 for things to work properly in u/s CI. The problem appears to be standalone specific.

This is fixed in 16.2 - bug 2102017
