ROUTE

Manipulates network routing tables. This command is available only if the TCP/IP protocol has been installed.

ROUTE /?

ROUTE [-f] [-p] [-s] [command [destination] [mask subnetmask] [gateway] [metric costmetric] [if interface]]

command (NT3.1)

Specifies one of:

• add Adds a route
• change Modifies an existing route
• delete Deletes a route
• print Prints a route

destination (NT3.1)

Specifies the computer to send command.

gateway (NT3.1)

Specifies gateway.

All symbolic names used for destination or gateway are referenced in both the network database file called Networks, and the computer name database file called Hosts. If the command is print or delete, wildcards may be used for the destination and gateway, or the gateway argument may be omitted.

if interface (NTXP)

Specifies the interface index for the interface over which the destination is reachable. For a list of interfaces and their corresponding interface indexes, use the display of the route print command. You can use either decimal or hexadecimal values for the interface index. For hexadecimal values, precede the hexadecimal number with 0x. When the if parameter is omitted, the interface is determined from the gateway address.

mask subnetmask (NT3.5)

Specifies a subnet mask to be associated with this route entry. If not specified, 255.255.255.255 is used.

metric costmetric (NT2000)

Assigns an integer cost metric (ranging from 1 to 9999) to be used in calculating the fastest, most reliable, and/or least expensive routes.

/? (NTXP)

Displays help.

-f (NT3.1)

Clears the routing tables of all gateway entries. If this is used in conjunction with one of the commands, the tables are cleared prior to running the command.

-p (NT2000)

When used with the add command, makes a route persistent across boots of the system. By default, routes are not preserved when the system is restarted. When used with the print command, displays the list of registered persistent routes. Ignored for all other commands, which always affect the appropriate persistent routes.

Only supported on the route command for Windows NT 4.0, Windows 2000, Windows Millennium Edition, and Windows XP. Not supported by the route command for Windows 95 or Windows 98.

-s (NT3.1 ONLY)

The operation refers to the smart gateway. One smart gateway may be specified; packets for which no destination is found in the gateway table are routed to the smart gateway. The destination field is not specified when this option is in use.
