comprises a set of if-match and apply clauses. The if-match clauses define the
matching rules. The matching objects are some attributes of routing information. The
relationship among the if-match clauses for a node is "AND". As a result, a matching
test against a node is successful only when all the matching conditions specified by
the if-match clauses in the node are satisfied. The apply clauses specify the actions
performed after a matching test against the node is successful, and the actions can be
the attribute settings of routing information.
There is an OR relationship between different nodes in a routing policy. As a result,
the system examines the nodes in the routing policy in sequence, and once the route
matches a node in the routing policy, it will pass the matching test of the routing policy
without entering the test of the next node.

6.2 IP Routing Policy Configuration Task List

Complete the following tasks to configure an IP routing policy:

Routing Policy Configuration

IP-Prefix Configuration
AS Path List Configuration
Community List Configuration
6.3 Routing Policy Configuration
A routing 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 routing policy can comprise multiple nodes and each node comprises:
if-match clause: Defines matching rules; that is, the filtering conditions that the
routing information should satisfy for passing the current routing policy. The
matching objects are some attributes of the routing information.
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.
