Enter the Loopback interface used as the source interface of a VXLAN virtual tunnel, from 0 to 16383.

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.

Examples
