= Configuration for a dummy device additional network
|
|
|
|
[role="_abstract"]
|
|
The dummy CNI plugin functions like a loopback device. The plugin is a virtual interface, and you can use the plugin to route the packets to a designated IP address. Unlike a loopback device, the IP address is arbitrary and is not restricted to the `127.0.0.0/8` address range.

|
|
|
The dummy device CNI plugin JSON configuration object describes the configuration parameters for the dummy CNI plugin. The following table details these parameters:
