Precautions
1) When you configure the apply cost command in a route policy:
The new cost should be greater than the original one to prevent RIP from generating routing loop in
the case that a loop exists in the topology.
The cost will become 16 if you try to set it to a value greater than 16.
The cost will become the original one if you try to set it to 0.
The cost will still be 16 if you try to set it to 16.
2) Using the if-match interface command will match the routes whose outgoing interface to the next
hop is the specified interface.
3) You are recommended to configure a node to match all routes not passing the preceding nodes in
a route policy.
4) If the cost of a received RIP route is equal to 16, the cost specified by the apply cost command in
a route policy will not be applied to the route, that is, the cost of the route is equal to 16.
5) Using the filter-policy command does not filter redistributed routes.

Troubleshooting IP Route Policy

Symptom
The route policy cannot filter routing information correctly when the routing protocol runs normally.
