Custom vRouter settings

Available since MOS 21.2 TechPreview

To specify custom settings for the Tungsten Fabric (TF) vRouter nodes, for example, to change the name of the tunnel network interface or enable debug level logging on some subset of nodes, use the customSpecs settings in the TFOperator CR.

For example, to enable debug level logging on a specific node or multiple nodes:

spec:
  controllers:
    tf-vrouter:
      agent:
        customSpecs:
        - name: debug
          label:
            name: <NODE-LABEL>
            value: <NODE-LABEL-VALUE>
          containers:
          - name: agent
            env:
            - name: LOG_LEVEL
              value: SYS_DEBUG

The customSpecs parameter inherits all settings for the tf-vrouter containers that are set on the spec:controllers:agent level and overrides or adds additional parameters. The example configuration above overrides the logging level from SYS_INFO, which is the default logging level, to SYS_DEBUG.

Starting from MOS 21.6, for clusters with a multi-rack architecture, you may need to redefine the gateway IP for the Tungsten Fabric vRouter nodes using the VROUTER_GATEWAY parameter. For details, see Multi-rack architecture.
