Symptom 1: Routing information filtering cannot be implemented in normal 
operation of the routing protocol

Solution: Check for the following faults:

The if-match mode of at least one node of the Route-policy should be the permit 
mode. When a Route-policy is used for the routing information filtering, if a piece 
of routing information does not pass the filtering of any node, then it means that 
the route information does not pass the filtering of the Route-policy. When all the 
nodes of the Route-policy are in the deny mode, then all the routing information 
cannot pass the filtering of the Route-policy.
