You can configure static routes on an unnumbered Ethernet interface. To do so, you use the qualified-next-hop statement to specify the unnumbered Ethernet interface as the next-hop interface for a configured static route. This feature enables you to specify independent preferences and metrics for static routes on a next-hop basis.
For a configuration example that illustrates this feature, see Example: Configuring an Unnumbered Ethernet Interface as the Next Hop for a Static Route.
For information about how to specify an independent preference for a static route, see the JUNOS Routing Protocols Configuration Guide.
