if-match clauses: define the matching rules routing information must satisfy. The
matching objects are some attributes of routing information.
apply clauses: specifies the actions performed after specified matching rules
satisfied, concerning attribute settings for passed routing information.

3.3.1 Prerequisites

Before configuring this task, you have completed:
Filtering list configuration
Routing protocol configuration
You also need to decide on:
Name of routing policy, node sequence numbers
Matching rules
Attributes to be modified

3.3.2 Creating a Routing Policy

To create a routing policy, use the following commands:
To do...
Enter system view
Create a routing
policy and enter its
view
Note:
If a node is specified as permit, routing information meeting the node's conditions
will be handled using the apply clauses of this node, without needing to match the
next node. If routing information does not meet the node's conditions, it will go to the
next node for matching.
If a node is specified as deny, the apply clauses of the node will not be executed.
When routing information meets all if-match clauses, it cannot pass the node, nor
can it go to the next node. If route information cannot meet any if-match clause of
the node, it will go to the next node for matching.
When a routing policy is defined with more than one node, at least one node should
be configured using the permit keyword. If the routing policy is used to filter routing
information, routing information that does not meet any node's conditions cannot
pass the routing policy. If all nodes of the routing policy are set using the deny
keyword, no routing information can pass it.
Use the command...
