Creating a routing policy
A routing policy consists of one or more statements that contain the following:
Match conditions, such as protocol type, AS path length, and address family, against which routes are evaluated
Actions, such as accept or reject, for routes that match the conditions in the statement
Each statement has a specified sequence number. If a policy has multiple statements, they are processed in sequence-number order. In addition, you can specify a default action that applies to routes that do not match any statement in the policy.
