Virtualization Support

IPv4 supports Virtual Routing and Forwarding instances (VRFs). VRFs exist within virtual device
contexts (VDCs). By default, Cisco NX-OS places you in the default VDC and default VRF unless you
specifically configure another VDC and VRF. For more information, see the Cisco NX-OS Virtual Device
Context Configuration Guide and see
