route

route [options] [command]

TCP/IP command. Add or remove entries in the routing tables maintained by routed. route accepts two commands: add, to add a route, and del, to delete a route. The two commands have the following syntax:

						add [-net | -host]
						address [modifiers]
del [-net | -host]
						address [modifiers]

address is treated as a plain route, unless -net is specified or address is found in /etc/networks. -host can be used to specify that address is a plain route whether or not it is found in /etc/networks. Using route modifiers, you can specify the gateway through which to route packets headed for that address, its netmask, TCP mss, or the device with which to associate the route; you can also mask certain routes. Only a privileged user may modify the routing tables.

If no command is specified, route prints the routing tables.
