Defining a Route Policy

Follow these steps to define a route policy:

To do...

Use the command...

Remarks

Enter system view

system-view

Define a route policy and enter
the route policy view

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.

Defining if-match Clauses and apply Clauses

Follow these steps to define if-match clauses and apply clauses:

To do...

Use the command...

Remarks

Enter system view

system-view

Enter the route-policy view

route-policy

route-policy-name

{ permit |

deny

} node node-number

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.
