Interfaces Configuration Statements
When configuring the interfaces, you can configure the interfaces that are currently present in the router (that is, the PICs that are already installed in the router) as well as interfaces that you might be adding at some future time (that is, PICs that you plan to install). To determine which interfaces are currently installed in the router, use the show interfaces terse command from the top-level CLI. If an interface is listed in the output, it is installed in the router. If an interface is not listed, it is not present.
The router software automatically configures the router's management Ethernet interface, fxp0, which is an out-of-band management interface, and the internal Ethernet interface, fxp1, which connects the Routing Engine to the control board (SCB, SSB, FEB, or SFM). The software also automatically configures one loopback interface, lo0.
Complete Interfaces Configuration Statements
To configure router interfaces, you include statements at the [edit interfaces] hierarchy level of the configuration:

Minimum Interface Configuration
For your router to function properly, you must configure each PIC interface that is present in the router. No PIC interfaces are preconfigured.
