Routing Policies Overview

A routing policy has a major impact on the flow of routing information or packets within and through the device. The match conditions and actions allow you to configure a customized policy to fit your needs.

Routing protocols send information about routes to a router's neighbors. This information is processed and used to create routing tables, which are then distilled into forwarding tables. Routing policies control the flow of information between the routing protocols and the routing tables and between the routing tables and the forwarding tables. Using policies, you can determine which routes are advertised, specify which routes are imported into the routing table, and modify routes to control which routes are added to the forwarding table.

To create a routing policy, you configure criteria against which routes are compared, and the action that is performed if the criteria are met.
