11.7 PBR routing policy configuration
11.7.1 Configuration algorithm of Route-map for BGP
Route-maps may serve as filters processing routing information when it is received from or sent to the
neighbouring device. Processing may include filtering based on various route criteria and setting attributes
(MED, AS-PATH, community, LocalPreference, etc.) for the respective routes.
Also, Route-map may assign routes based on access control lists (ACL).
