By default, no matching will be performed.
Pay attention to the following:
The if-match clauses for a node in the route-policy have the relationship of "AND"
for matching. That is, the route must satisfy all the clauses to match the node
before the actions specified by the apply clauses can be executed.
If no if-match clauses are specified, all the routes will pass the filtering on the
node.
III. Defining apply clauses for a route-policy
The apply clauses specify actions, which are the configuration commands executed
after a route satisfies the filtering conditions specified by the if-match clauses. Thereby,
some attributes of the route can be modified.
Perform the following configuration in route-policy view.
