IP Routing Policy 155
By default, no matching is performed.
The if-match clauses for a node in the route policy require that the route 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 pass the filtering on the node.
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 that are specified in the
if-match clauses. In this way, some attributes of the route can be modified.
Perform the following configurations in Route policy view.
By default, no apply clauses are defined.
