The JUNOS policy architecture is simple and straightforward. However, the actual implementation of each policy adds layers of complexity to the policy as well as adding power and flexibility to your router’s capabilities. Configuring a policy has a major impact on the flow of routing information or packets within and through the router. For example, you can configure a routing policy that does not allow routes associated with a particular customer to be placed in the routing table. As a result of this routing policy, the customer routes are not used to forward data packets to various destinations and the routes are not advertised by the routing protocol to neighbors.
Before configuring a policy, determine what you want to accomplish with it and thoroughly understand how to achieve your goal using the various match conditions and actions. Also, make certain that you understand the default policies and actions for the policy you are configuring.
