source-interface loopback
Configures a dedicated Loopback interface as the source VTEP.
Syntax
source-interface loopback number
Parameters
loopback
number
Enter the Loopback interface used as the source interface of a VXLAN virtual
tunnel, from 0 to 16383.
Default Not configured
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 configured. 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 configured
for the NVE instance.
Use this command in NVE mode to override a previously configured value and reconfigure the source IP
address. The no version of this command removes the configured value.
