win xp 在cmd mode 下用route add 的指令會不會自動消失的？？

route add 預設是會在重新啓動後消失的，追加-p參數就可以在重新啓動後保存route add項目。此參數於Windows 95 下無效。

見route /?

Manipulates network routing tables.

ROUTE [-f] [-p] [command [destination]
[MASK netmask] [gateway] [METRIC metric] [IF interface]

-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.
-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
