Network traffic types within Cloud Foundation are isolated from each other through the use of VLANs. Before deploying your SDDC, you must allocate VLAN IDs and IP subnets for each required traffic type.

You must configure the VLAN IDs and IP subnets in your network in order to pass traffic through your network devices. Verify the allocated network information is configured and does not conflict with pre-existing services before starting your Cloud Foundation deployment.

The number and size of the subnets required for a deployment will depend on the number of workload domains created, the number of clusters defined, and the optional components installed.

The following table demonstrates the basic allocation of VLANs and IP subnets for a sample deployment. Utilize this sample to define the actual VLANs and IP subnets according to your environment.
