You can define preference in the /etc/gated.conf file configuration file in the following instances:

In the static route definition in the Static class. This preference definition sets the preference for static routes. (See “Customizing Routes” on page 90 for more information.) If this option is not set, the preference values for static routes is 60.

In the interface statement options in the Interface class. This preference definition sets the preference for routes to this interface. If this option is not set, the preference value is 0. For more information, type man 4 gated.conf at the HP-UX prompt.
