This object classifies the route as other, invalid, a directly connected network, or an indirect route requiring a next-hop gateway. Admins use it to distinguish local, directly attached routes from those learned or configured toward remote networks, and setting it to invalid(2) is the documented mechanism for deleting a route entry from the table. For example, an admin who wants to remove a stale static route would set its aniDevRouteType to invalid(2) to disassociate that destination from the table.
