The example presented in this chapter illustrates how you might configure a Layer 2 circuit with protect interfaces. Protect interfaces act as backups for their associated interfaces. The primary interface has priority over the protect interface and carries network traffic as long as it is functional. If the primary interface fails, the protect interface is activated. These interfaces can also share the same virtual path identifier (VPI) or virtual circuit identifier (VCI).
For more examples on how to configure Layer 2 circuits, see the JUNOS Feature Guide.
Figure 56 shows the network topology used in this example.
