Every provider VDC that is backed by NSX Data Center for vSphere includes a VXLAN network pool.
When you create a provider VDC that is backed by NSX Data Center for vSphere, you can associate that provider VDC with an existing VXLAN network pool, or you can create a VXLAN network pool for the provider VDC.
A newly created VXLAN network pool is given a name derived from the name of the containing provider VDC and attached to it at creation. You cannot delete or modify this network pool. If you rename a provider VDC, its VXLAN network pool is automatically renamed.
vCloud Director VXLAN networks are based on the IETF VXLAN standard, and provide various benefits.
- Logical networks spanning layer 3 boundaries
- Logical networks spanning multiple racks on a single layer 2
- Broadcast containment
- Higher performance
- Greater scale (up to 16 million network addresses)
For more information about VXLAN networks in a vCloud Director environment, see the NSX Administration Guide.
