    Linux Route Flags (U – Up, G – Gateway, H – Host)


    Following is the list of flags and their significance in the routing table :

        U : This flag signifies that the route is up
        G : This flag signifies that the route is to a gateway. If this flag is not present then we can say that the route is to a directly connected destination
        H : This flag signifies that the route is to a host which means that the destination is a complete host address. If this flag is not present then it can be assumed that the route is to a network and destination would be a network address.
        D : This flag signifies that this route is created by a redirect.
        M : This flag signifies that this route is modified by a redirect.
