Configuring a Routing Policy
As shown in Figure 1, you use import routing policies to control which routes routing protocols place in the routing table, and export routing policies to control which routes a routing protocol advertises from the routing table to its neighbors.
Figure 1: Importing and Exporting Routing Policies
To create a routing policy, you must define the following components:
- Match conditions—Criteria that a route must match. If a route matches all of the criteria, one or more actions are applied to the route.
- Actions—What to do if a route matches. The actions can specify whether to accept or reject the route, control how a series of policies is evaluated, and manipulate the characteristics associated with a route. You can configure one or more actions.
You typically define match conditions and actions within a term. Figure 2 shows the routing policy components, including the term.
Figure 2: Routing Policy Components
After defining a routing policy, you then apply it to a routing protocol or to the forwarding table.
