Overview of Layer 3 Virtualization

Cisco NX-OS supports a hierarchy of virtualization that can divide the physical system resources into multi-
ple virtual device contexts (VDCs). Each VDC acts as a standalone device with both Layer 2 and Layer 3
services available. You can configure up to 4 VDCs, including the default VDC. See the Cisco NX-OS Virtu-
alization Configuration Guide for more information on VDCs.
