5.3 Route-Policy Configuration
A route-policy is used to match given routing information or some attributes of routing
information and change the attributes of the routing information if the conditions are
met. The above-mentioned filtering lists can serve as the match conditions:
A route-policy can comprise multiple nodes and each node comprises:
z if-match clause: Defines matching rules; that is, the filtering conditions that the
routing information should satisfy for passing the current route-policy. The
matching objects are some attributes of the routing information.
z apply clause: Specifies actions, which are the configuration commands
executed after a route satisfies the filtering conditions specified by the if-match
clause. Thereby, some attributes of the route can be modified.
