Description Preference value for a static, aggregate, or generated route. You also can specify a
secondary preference value, as well as color values, which are even finer-grained
preference values.
You can specify a primary route preference (by including the preference statement in
the configuration), and a secondary preference that is used as a tiebreaker (by including
the preference2 statement). You can also mark route preferences with additional route
tiebreaker information by specifying a color and a tiebreaker color (by including the color
and color2 statements in the configuration).
If the Junos OS routing table contains a dynamic route to a destination that has a better
(lower) preference value than the static, aggregate, or generated route, the dynamic
route is chosen as the active route and is installed in the forwarding table.
Options metric_value—The metric value for an aggregate, a generated, or a static route to determine
the best route among multiple routes to a destination
