Windows Route Command

角色

一般我们用Windows，根本不会用route command的，但是为了routing，大家最好对Windows Route Command要有认识。

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. 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. This option is not supported Windows'95 command.

command  One of these:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route destination

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*.

Diagnostic Notes:
Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
Example> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1 IF 1
The route addition failed: The specified mask parameter is invalid.
(Destination & Mask) != Destination.

Examples

Examples:

> route PRINT

>route ADD 157.0.0.0
                     ^destination

MASK 255.0.0.0
             ^mask            157.55.80.1   
    ^gateway        METRIC 3
^metric        IF 2
^Interface
If IF is not given, it tries to find the best interface for a given
gateway.

> route PRINT
> route PRINT 157* .... Only prints those matching 157*
> route DELETE 157.0.0.0
> route PRINT
