Assigning to networking for clarification on what needs to be done in config. We also need to consider what we need to do during upgrades. Cluster Lifecycle team can help implement changes but we need to be told exactly what to do. no clusterNetworks config information found in v3.5.5.31.34 either, look like this is not a bug.

And the old clusterNetworkCIDR and hostSubnetLength will be deprecated in master config. There is a 3.7 new feature, so 3.5 won't have clusterNetworks in master config.
And this should be a OCP openshift-ansible bug, since the master config of OCP is generated by openshift ansible:
networkConfig:
clusterNetworkCIDR: {{ openshift.master.sdn_cluster_network_cidr }}
hostSubnetLength: {{ openshift.master.sdn_host_subnet_length }}
{% if r_openshift_master_use_openshift_sdn or r_openshift_master_use_nuage or r_openshift_master_use_contiv or r_openshift_master_sdn_network_plugin_name == 'cni' %}
networkPluginName: {{ r_openshift_master_sdn_network_plugin_name_default }}
{% endif %}
# serviceNetworkCIDR must match kubernetesMasterConfig.servicesSubnet
serviceNetworkCIDR: {{ openshift.common.portal_net }}
externalIPNetworkCIDRs: {{ openshift_master_external_ip_network_cidrs | default(["0.0.0.0/0"]) | to_padded_yaml(1,2) }}
{% if openshift_master_ingress_ip_network_cidr is defined %}
ingressIPNetworkCIDR: {{ openshift_master_ingress_ip_network_cidr }}
{% endif %}
openshift v3.7.0-0.188.0
kubernetes v1.7.6+a08f5eeb62
clusterNetworks already exist in master-config now.
networkConfig:
clusterNetworkCIDR: 10.128.0.0/14
clusterNetworks:
- cidr: 10.128.0.0/14
hostSubnetLength: 9
externalIPNetworkCIDRs:
- 0.0.0.0/0
hostSubnetLength: 9
networkPluginName: redhat/openshift-ovs-subnet
serviceNetworkCIDR: 172.30.0.0/16
