Policies
Associate a routing policy when configuring an aggregate or generated route's destination prefix in
the routes part of the aggregate or generate statement. This provides the equivalent of an import
routing policy filter for the destination prefix. That is, each potential contributor to an aggregate
route, along with any aggregate options, passes through the policy filter. The policy then can accept
or reject the route as a contributor to the aggregate route and, if the contributor is accepted, the
policy can modify the default preferences. The contributor with the numerically smallest prefix
becomes the most preferred, or primary, contributor. A rejected contributor still can contribute to a
less specific aggregate route. If you do not specify a policy filter, all candidate routes contribute to
an aggregate route. Move policies from
Available to Selected with the arrows between those panels.
You can also reorder the
Selected policies with the up/down arrows below that panel.

Click Apply to accept your edits, or Cancel to abandon them. When you Add or Edit , the following
fields appear in an editor:
-
Destination Prefix —Network portion of the IP address, and prefix-length is the destination
prefix length.
-
No Install —Configure whether the JUNOS software installs all static routes into the forwarding
table. Even if you configure a route so it is not installed in the forwarding table, the route is
still eligible to be exported from the routing table to other protocols. Do not install the route
into the forwarding table, even if it is the route with the lowest preference.
-
Preference —This is a value for a static, aggregated, or generated route. A lower number indicates
a more preferred route. Range: 1 through 255 Default: 5 (for static routes), 130 (for aggregate
and generated routes)
-
Metric —Metric value for an aggregate, generated, or static route. Range: 1 through 65,535.
