IP Routing Policy 261
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 will 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.
Importing Routing Information Discovered by Other Routing Protocols
A routing protocol can import the routes that are discovered by other routing
protocols to enrich its route information. The route policy can filter route information
to implement the redistribution. If the destination routing protocol that imports the
routes cannot directly reference the route costs of the source routing protocol, you
should satisfy the requirement of the destination protocol by specifying a route cost
for the imported route.
