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

Select IP Routing > Policy from the Device Manager menu. The

Policy dialog opens with the Preﬁx List tab selected. This tab

is illustrated below.
