Overview

Creating policies involves specifying the following:

• match criteria--used to determine whether or not the policy will be applied to a route
• set parameters--used in controlling router advertisements
• action--used to determine whether to announce/accept or ignore the route that meets the matching criteria of the policy

A policy may be applicable for routes to a single network or a list of networks. Match criteria for such policies are specified in terms of network lists. A network list is created by grouping one or more network addresses together. Prior to use, the networks that are used in network lists should be entered in the network address table.

A policy may also be applicable for routes learned over specific interfaces or from specific gateways. Match criteria for such policies are specified in terms of interface/router lists. An interface/router list is created by grouping one or more IP addresses from the interface/router table. Prior to use, the IP addresses used in the interface/router lists should be entered in the interface/router table.
