Hehe I have no idea. The route(8) utility manually adds routes to the routing table. Since i have no idea what your network configuration is, I can't tell you if it's 'working properly' or not.
Maybe that line adds a route to help load-balance on your LAN or something, but it could connect perfectly well without it.
Call whomever told you to add that line to your start-up routine and ask them if it's 'working'.
