Routing Policy Overview

A routing policy is a mechanism that allows a user to configure criteria to compare a routing update against, with one or more actions to be performed on the route if the defined criteria are met. For example, a policy can be created to filter (block) specific route prefixes that are being announced by a BGP neighbor. Policy statements are also used to export routes learned via one protocol, for instance OSPF, into another protocol, for instance BGP. This is commonly called route redistribution.
