Currently, Flag can have the following values:

D: a route generated by a dynamic routing protocol such as Intermediate System to Intermediate System routing protocol (IS-IS), open shortest path first (OSPF), Border Gateway Protocol (BGP), or Routing Information Protocol (RIP).

G: a gateway route, that is, a route with a gateway as the destination address.

H: a host route.
