ROUTE manipulates network routing tables.
-f: 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.
ROUTE [-f] [-p] [command [destination] [MASK netmask] [gateway] [METRIC metric] [IF interface]
-p: 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. Ignored for all other commands, which always affect the appropriate persistent routes. This option is not supported in Windows 95.
command: One of these:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route
destination: Specifies the host.
MASK: Specifies that the next parameter is the 'netmask' value.
netmask: Specifies a subnet mask value for this route entry. If not specified, it defaults to 255.255.255.255.
gateway: Specifies gateway.
interface: the interface number for the specified route.
METRIC: specifies the metric, ie. cost for the destination.
All symbolic names used for destination are looked up in the network database file NETWORKS. The symbolic names for gateway are looked up in the host name database file HOSTS.
If the command is PRINT or DELETE. Destination or gateway can be a wildcard, (wildcard is specified as a star '*'), or the gateway argument may be omitted.
If Dest contains a * or ?, it is treated as a shell pattern, and only matching destination routes are printed. The '*' matches any string, and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.
route ADD 188.8.131.52 MASK 255.0.0.0 184.108.40.206 METRIC 3 IF 2
destination^ ^mask ^gateway metric^ ^Interface^
If IF is not given, it tries to find the best interface for a given gateway.
route PRINT 157* .... Only prints those matching 157*
route CHANGE 220.127.116.11 MASK 255.0.0.0 18.104.22.168 METRIC 2 IF 2
CHANGE is used to modify gateway and/or metric only.
route DELETE 22.214.171.124
