By now, you should have a vSphere cluster with the VXLAN and segment ID range configured, as covered in previous recipes. When creating a transport zone, a replication mode must be chosen. See the Introduction section to understand the replication mode options and what to consider.
Once a replication mode has been chosen, you can still change it later in the transport zone level by editing the created transport zone. For example, you can create a unicast transport zone first and then once you scale to a larger network and want to offload some function to the physical network, you can migrate the transport zone from unicast to hybrid.
