Defining a Route Policy 
Follow these steps to define a route policy: 
To do... 
Use the command... 
Remarks 
Enter system view 
system-view 
— 
Define a route policy and enter 
the route policy view 
route-policy route-policy-name { permit 
deny node node-number 
Required 
Not defined by default 
 
 
The permit argument specifies the matching mode for a defined node in the route policy to be in 
permit  mode. If a route matches the rules for  the node, the apply  clauses for the node will be 
executed and the test of the next node will not be taken. If not, however, the route takes the test of 
the next node. 
The deny argument  specifies the matching mode for a defined node in the route policy to be in 
deny mode. In this mode, no apply clause is executed. If a route satisfies all the if-match clauses 
of the node, no apply clause for the node will be executed and the test of the next node will not be 
taken. If not, however, the route takes the test of the next node. 
If multiple nodes are defined in a route policy, at least one of them should be in permit mode. When 
a route policy is applied to filtering routing information, if a piece of routing information does not 
match any node, the routing information will be denied by the route policy. If all the nodes in the 
route policy are in deny mode, all routing information will be denied by the route policy.

Required 
Define a rule to match the 
IP address of routing 
information 
if-match { acl acl-number | 
ip-prefix ip-prefix-name } 
Optional 
By default, no matching is performed on 
the address of routing information.
