Doc Type: Known Issue
Doc Text:
In Red Hat OpenStack Platform (RHOSP) deployments that use the Modular Layer 2 plug-in with the Open vSwitch (ML2/OVS) mechanism driver, there is currently a known issue where the Orchestration service (heat) parameter, `NeutronL3AgentAvailabilityZone` does not set the relevant Neutron L3 agent parameter correctly. + Workaround: use a custom hieradata statement to set this value. In the example that follows, replace `[ROLE]` with the composable role name that is appropriate for your site. + .Example + ---- [ROLE]ExtraConfig: neutron::agents::l3::availability_zone: role_availability_zone ---- + https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.2/html/advanced_overcloud_customization/assembly_configuration-hooks#proc_puppet-customizing-hieradata-for-roles_configuration-hooks For more information, see link:[Puppet: Customizing hieradata for roles] in the _Advanced Overcloud Customization_ guide.

Description Marian Krcmarik 2021-07-19 16:20:50 UTC 
Description of problem:
If the NeutronL3AgentAvailabilityZone THT paramater is used the specified value of AZ for L3 agent is not being set, instead the default value "nova" is set for Neutron Availability zone of L3 agent.
The similar parameter NeutronDhcpAgentAvailabilityZone works as expected as well as setting it as ExtraConfig parameter for the role works as expected too, for example:
  Controller0ExtraConfig:
      neutron::agents::l3::availability_zone: az-central

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Use NeutronL3AgentAvailabilityZone parameter for setting AZ of Neutron L3 agent in tripleo heat templates.

Actual results:
The value of "nova" is set as AZ for L3 agent.

Expected results:
The specified value of the parameter should be set as the Neutron AZ for L3 agent.

Comment 2 Bernard Cafarelli 2021-07-23 10:24:11 UTC 
Confirmed, the parameter is currently ignored, there is a typo in deployment/neutron/neutron-l3-container-puppet.yaml:
          -
          - if:
            - az_unset
            - {}
            - neutron::agents::l3::availability_zone: {get_param: NeutronL3AgentAvailabilityZone}
            if:
            - l3_agent_extensions_empty
            - {}
            - neutron::agents::l3::extensions: {get_param: NeutronL3AgentExtensions}

That second if should not be in same item. This was fixed in the middle of larger commit https://opendev.org/openstack/tripleo-heat-templates/commit/27788212ccaff768fbf192d6a16e478d6bfc75bb in wallaby, so parameter is broken in earlier stable versions.
