NSX-T resources must be created to provide networking to OpenShift nodes. You can configure these resources manually using the NSX Manager GUI, or automate the process using an Ansible playbook.
This chapter describes creating the NSX-T resources manually. To automate the process, see Install CNI Plug-in and OVS. Note that if you create the resources using a playbook, for SNAT, you can only create an IP block, whereas if you create the resources manually, you can create either an IP block or IP pool for SNAT.
