permit means applying policy routing for the packets meeting the conditions, and deny
means not applying policy routing for the packets meeting the conditions.
By default, no route-policy and the related node configuration is defined.
II. Defining if-match clauses for the route-policy
The if-match clauses are used for matching packets on which policy routing is to be
performed. IP unicast policy routing provides two if-match clauses, if-match
packet-length clause and if-match acl clause. When both of them are configured,
their relationship is AND.
Perform the following task in route-policy view.
Table 12-2 Define if-match clause of policy routing
Specify an IP packet length if-match
clause
Specify an ACL matching if-match
clause
By default, no if-match clause is defined.
III. Defining the apply clauses of the route-policy
IP unicast policy routing provides five types of apply clauses: apply ip-precedence,
apply output-interface, apply ip-address next-hop, apply default output-interface,
and apply ip-address default next-hop. One route-policy node may have multiple
apply clauses. These clauses are executed in the order in which they are configured
until a valid apply clause is executed.
Perform the following task in route-policy view.
