Verify contrail-vrouter-agent¶

While troubleshooting OpenContrail, you may have issues with the contrail-vrouter-agent configuration that fails to be created.

To verify the contrail-vrouter-agent configuration:

1. Log in to any OpenStack compute node.

2. Verify whether the global vRouter configuration is created:

   contrail-status
   

   Example of system response:

    == Contrail vRouter ==
    supervisor-vrouter:           active
    contrail-vrouter-agent        initializing (No Configuration for self)
    contrail-vrouter-nodemgr      active
   

   If the status is active, the configuration is created successfully. If the contrail-vrouter-agent status is initializing (No Configuration for self), proceed to the next step.

3. Use either the OpenContrail web UI or SaltStack commands to create the global vRouter configuration:

   • Using the OpenContrail web UI:

     1. Log in to the OpenContrail web UI as admin.
     2. Go to Configure > Infrastructure > Global Config.
     3. On the right side above the table, click Edit. If the global configuration is missing, the window with default values opens.
     4. Click Save.

   • Using SaltStack:

     1. Log in to the Salt Master node.

     2. Depending on your deployment, apply one of the following states:

        • For Kubernetes:

          salt 'ctl01*' state.sls opencontrail.client
          

        • For OpenStack:

          salt 'ntw01*' state.sls opencontrail.client
          

     3. Verify if global-vrouter-config was created:

        • For Kubernetes:

          salt 'ctl01*' contrail.global_vrouter_config_list
          

        • For OpenStack:

          salt 'ntw01*' contrail.global_vrouter_config_list
          

        Note

        If the output is empty, add system.opencontrail.client.resource.global_vrouter_config as the last system class in /srv/salt/reclass/classes/cluster/k8s-ha-contrail-40/opencontrail/control.yml and reapply the opencontrail.client state for Kubernetes or OpenStack as described in the step 2.

     4. Verify the contrail-vrouter-agent status:

        salt 'cmp*' cmd.run "contrail-status"
        

     5. If global-vrouter-config is still missing, perform the following manual steps:

        1. Log in to any OpenContrail controller node, for example, ntw01.

        2. Run the following command:

           salt-call contrail.global_vrouter_config_create name="global-vrouter-config" \
           parent_type="global-system-config" encap_priority="MPLSoUDP,MPLSoGRE" \
           vxlan_vn_id_mode="automatic" \
           fq_names=['default-global-system-config','default-global-vrouter-config']
           

4. Verify that the global vRouter configuration is created successfully and is in the active status using the contrail-status command.
