Defining a Route Policy
Follow these steps to define a route policy:

route-policy
route-policy-name { permit |
deny
} node node-number
Required
Not defined by default
z
The permit argument specifies the matching mode for a defined node in the route policy to be in
permit
mode. If a route matches the rules for the node, the apply clauses for the node will be
executed and the test of the next node will not be taken. If not, however, the route takes the test of
the next node.
z
The deny argument specifies the matching mode for a defined node in the route policy to be in
deny
mode. In this mode, no apply clause is executed. If a route satisfies all the if-match clauses
of the node, no apply clause for the node will be executed and the test of the next node will not be
taken. If not, however, the route takes the test of the next node.
z
If multiple nodes are defined in a route policy, at least one of them should be in permit mode. When
a route policy is applied to filtering routing information, if a piece of routing information does not
match any node, the routing information will be denied by the route policy. If all the nodes in the
route policy are in deny mode, all routing information will be denied by the route policy.

Required
Define a rule to match the IP
address of routing
information
if-match
acl acl-number
Optional
By default, no matching is performed on the
address of routing information.
Define a rule to match the
cost of routes
if-match cost value
Optional
By default, no matching is performed against
the cost of routes.
Define a rule to match the
next-hop interface of routing
information
if-match interface
interface-type
interface-number
Optional
By default, no matching is performed on the
next-hop interface of routing information.
