The IP address of a loopback interface is usually specified as the source address of packets.
After a loopback interface is created, you can use command set l3-interface loopback vrf to bind the loopback interface to a VRF. Users can configure multiple loopback interfaces per VRF. A loopback interface is in the default VRF by default.
You can also use command set l3-interface loopback disable to disable a loopback interface. When a loopback interface is created, it is enabled by default.
Note that lo is a built-in loopback interface in default VRF, it cannot be bound to any other user-defined VRF, or be disabled.
Example
- Create a loopback interface lo-gre in the default VRF.
