User Guidelines
The VRF identified in the parameter must have been previously created or an
error is returned.
Only IPv4 addresses are supported with the vrf parameter.
The vrf parameter is only available on the N3000-ON/N3100-ON/N3200-ON
switches.
The interface identifier is the identifier of the unnumbered interface, not the
loopback interface from which the IP address is borrowed.
When the IP address does not uniquely identify an ARP entry, the interface
must be given to uniquely identify the ARP entry. The interface may be
numbered or unnumbered.
