Synthetic devices are often used as a proxy for environments that are not under the direct management of the user, and as such they cannot be collected from and consequently modeled in Forward. For example, a modeled device at the edge of the network would have one or more interfaces and their sub-interfaces connected to a given synthetic node which represents a Service Provider peering.
There have been cases in which the user connects only a subset of sub-interfaces to a synthetic node, leaving the rest of them "orphaned". This incomplete configuration leads to traffic egressing those interfaces and being black-holed by the Forward model.
The 23.8 release introduces a new synthetic device called Missing Peer that models such traffic. Unlike other synthetic devices, this new device is not configured by the user but is automatically created by the Forward platform. A config property will allow Org Admins to enable or disable the creation of these synthetic devices.
