RTF_PRCLONING is set automatically by the protocol to cause host routes to be generated on every unique lookup. RTF_CLONING is set when the route is added (either manually, or automatically for interface routes) to indicate that a more specific route (possibly a host route) needs to be generated on every unique lookup. RTF_XRESOLVE is set when the target of the newly cloned route is not known by the kernel and must be set up by a user process. I'm not sure if anything ever used this, although I guess it could be used to implement ISIS. -GAWollman
