For ACL configuration, refer to the part discussing ACL.

Route policy

A route policy is used to match some attributes with given routing information and the attributes of the information will be set if the conditions are satisfied.

A route policy can comprise multiple nodes. Each node is a unit for matching test, and the nodes will be matched in ascending order of their node numbers. Each node comprises a set of if-matchand apply clauses. The if-matchclauses define the matching rules. The matching objects are some attributes of routing information. The relationship among the if-matchclauses 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-matchclauses 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 route policy. As a result, the system examines the nodes in the route policy in sequence, and once the route matches a node in the route policy, it will pass the matching test of the route policy without entering the test of the next node.

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

z

if-matchclause: 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.

apply clause: Specifies actions, which are the configuration commands executed after a route satisfies the filtering conditions specified by the if-matchclause. Thereby, some attributes of the route can be modified.

Configuration Prerequisites

Before configuring a route policy, perform the following tasks:

z

z

Configuring a filtering list, Configuring a routing protocol

Prepare the following data before the configuration:

zRoute policy name and node number
