Parameters
loopback
number
Enter the Loopback interface used as the source interface of a VXLAN virtual tunnel,
from 0 to 16383.
Default Not congured
Command mode NVE-INSTANCE
Usage information
The IP address of the Loopback interface serves as the source IP address in encapsulated packets transmitted
from the switch as an NVE VTEP.
• The Loopback interface must have an IP address congured. The Loopback IP address must be reachable from
the remote VTEP.
• You cannot change the source interface if at least one VXLAN virtual network ID (VNID) is congured for the
NVE instance.
Use this command in NVE mode to override a previously congured value and recongure the source IP address.
The no version of this command removes the congured value.
