IP Routing Policy Configuration Commands 235
■ Use the filter-policy import command to set the condition for filtering the
routing information.

condition
By default, the received routing information is not filtered.
In some cases, it may be required that only the routing information meeting some
conditions can be received. Then, the filter-policy command can be used to set the
filtering conditions for the routing information to be advertised. Only the routing
information passing the filtration can be received.
Related command: filter-policy export.
Example
Define the filtering rule for receiving routing information of RIP. Only the routing
information filtered through the address prefix list p1 can be received by RIP.
