                not the final destination. 

                Routes which do not result in traffic forwarding or 
                rejection should not be displayed even if the  
                implementation keeps them stored internally. 

                reject(2) refers to a route which, if matched, discards  
                the message as unreachable and returns a notification  
                (e.g. ICMP error) to the message sender.  This is used  
                in some protocols as a means of correctly aggregating  
                routes.

                discards the message silently.
