Description of problem:

I think this statement is confusing:

• The OVN-Kubernetes network plugin must be configured in local gateway mode, where ovnKubernetesConfig.gatewayConfig.routingViaHost=true.

it gives impression that routingViaHost=true configures local gateway mode more correct to state 

The OVN-Kubernetes network plugin must be configured in Local Gateway Mode, and routingViaHost must be enabled by setting ovnKubernetesConfig.gatewayConfig.routingViaHost=true."

an extension would be to verify that OVN-Kubernetes network plugin is in local gateway mode.

I think oc get network.operator cluster -o jsonpath='{.spec.defaultNetwork.ovnKubernetesConfig.gatewayConfig.mode}'

change mode: oc patch network.operator cluster --type=merge -p '{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"gatewayConfig":

}}}}'
