IP Routing Policy 145
By default, no matching is performed.
Note that:
■ 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.
Define 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.
Cancel the matched next-hop
of the routing information
undo if-match ip next-hop [ip-prefix ip-prefix-name ]
Match the routing cost of the
