Learn how to install, configure, and operate the Vyatta Network Operating System (Vyatta NOS) and Orchestrator, which help drive our virtual networking and physical platforms portfolio.

You may at times want to configure a smaller network prefix than /8 to the loopback interface. The example in this section shows how to assign the address to the loopback interface. When you finish the example, the interface is configured as in the following figure.

Figure 1. Configuring the loopback interface
