Precautions
1) When you configure the apply cost command in a route policy:
z 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.
z The cost will become 16 if you try to set it to a value greater than 16.
z The cost will become the original one if you try to set it to 0.
z 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.
