Route policies

Route policies are a Nortel proprietary improvement on existing routing schemes. Using existing routing schemes, packets are forwarded based on routes that have been learned by the router through routing protocols such as RIP and OSPF or through the introduction of static routes. Route policies introduce the ability to forward packets based on rule sets created by the network administrator. These rule sets, or policies, are then applied to the learned or static routes.

This section describes the configuration and management of route policies using the Java Device Manager.

Prefix List configuration

The Prefix List tab is used for the configuration of policy prefix lists. Prefix lists are the base item in a routing policy. Prefix lists contain lists of IP addresses with their associated masks that support the comparison of ranges of masks.

To configure a prefix list, following this procedure:

Step Action

1Select IP Routing > Policy from the Device Manager menu. The Policy dialog opens with the Prefix List tab selected. This tab is illustrated below.
