Filtering routes using access lists

Access lists can be used to filter routes for distance-vector protocols such as RIP and at redistribution points into link-state routing domains (like OSPF) where they can control which routes enter or leave the domain.

This section presents a sample configuration for RIP and route filtering policy. In it we first show a RIP configuration that distributes all known routes among three routers. Then we configure a route filtering policy using access lists to filter out advertisement of one network. The configuration example is based on the following reference diagram.
