Every Provider VDC includes a VXLAN network pool.

This pool is given a name derived from the name of the containing provider virtual datacenter and attached to it at creation. You cannot delete or modify this network pool. You cannot create a VXLAN network pool by any other method. 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 the following 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.
