Once a policy is created, it must be applied before it is active. You apply routing policies using the import and export statements at the Protocols>protocol-name level in the configuration hierarchy.
In the import statement, list the name of the routing policy to be evaluated when routes are imported into the routing table from the routing protocol.
In the export statement, list the name of the routing policy to be evaluated when routes are being exported from the routing table into a dynamic routing protocol. Only active routes are exported from the routing table.
To specify more than one policy and create a policy chain, list the policies using a space as a separator. If multiple policies are specified, the policies are evaluated in the order in which they are specified. As soon as an accept or reject action is executed, the policy chain evaluation ends.
