      2025-01-30: Closing pinged on a number of channels no response if issue raised regarding the already merged and QE'd PR we can address it then routingViaHost is enabled in the PR with guidance.
      2025-01-07: Still awaiting response will chase up today.
      2024-12-19: A follow up question from Arti Sood on https://github.com/openshift/openshift-docs/pull/85914 asking whether  routingViaHost to true is needed. I pinged Arti and asked her to test, I tried to verify but need to expand on test.
      2024-12-10: I have this https://github.com/openshift/openshift-docs/pull/85914 open already in same content so adding this line in here makes sense.

      Description of problem:

      With section https://docs.openshift.com/container-platform/4.17/networking/metallb/about-advertising-ipaddresspool.html#nw-metallb-configure-secondary-interface_about-advertising-ip-address-pool

      guidance is needed on how to set routingViaHost enabled.

      Additional info:

      1. Update the CNO YAML and add:

      apiVersion: operator.openshift.io/v1
      kind: Network
      metadata:
        name: cluster
      spec:
        clusterNetwork:
        - cidr: 10.128.0.0/14
          hostPrefix: 23
        serviceNetwork:
        - 172.30.0.0/16
        networkType: OVNKubernetes
        defaultNetwork:
          ovnKubernetesConfig:

       

      Alternative and maybe more straightforward: oc patch network.operator cluster -p '{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"gatewayConfig":

      {"routingViaHost": true}

      }}}}' --type=merge
