Junos documentation often refers to logical interfaces as what?

In Junos documentation, logical interfaces are indeed referred to as logical units. This terminology aligns with how Juniper Networks structures its networking devices and configurations. A logical unit is a subdivision of a logical interface, which can be configured to act independently, allowing for flexible network configurations without the need for additional physical interfaces. This means that a single physical interface can support multiple logical units, each of which can have its own IP address and settings. This abstraction simplifies network design and management by allowing multiple networks or services to be handled over fewer physical resources. The term emphasizes the modular and flexible nature of Junos' interface configuration capabilities.
