Defining a Route Policy
Follow these steps to define a route policy:
To do...
Enter system view
Define a route policy and enter
the route policy view
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.
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.
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...
Enter system view
Enter the route-policy
view
Define a rule to match the
IP address of routing
information
Define a rule to match the
cost of routes
Define a rule to match the
next-hop interface of
routing information
Use the command...
system-view
route-policy route-policy-name { permit
| deny } node node-number
Use the command...
system-view
route-policy
route-policy-name { permit
| deny } node node-number
if-match acl acl-number
if-match cost value
if-match interface
interface-type
