  • You are logged in to the cluster as a user with the cluster-admin role.
  • The cluster is installed on compatible infrastructure.

Procedure

  • To disable dynamic routing, enter the following command: 
    $ oc patch Network.operator.openshift.io/cluster --type=merge -p '{
      "spec": { "additionalRoutingCapabilities": null }
    }'
