Each Services Router can support types of interfaces that perform different functions. The router uses network interfaces to transmit and receive network traffic. For network interfaces to operate, you must configure properties such as logical interfaces, the encapsulation type, and certain settings specific to the interface type.
This chapter includes the following topics. For more information about interfaces, see Interfaces Overview and the JUNOS Network Interfaces Configuration Guide. To configure DSL interfaces, see Configuring Digital Subscriber Line Interfaces. To configure PPPoE interfaces, see Configuring Point-to-Point Protocol over Ethernet. To configure ISDN interfaces, see Configuring ISDN.
