The type of route.  Note that local(3) refers to a  
                route for which the next hop is the final destination;   
                remote(4) refers to a route for which the next hop is  
                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. This is used in  
                some protocols as a means of correctly aggregating  
                routes.
