経路情報を確認するコマンド(route.exe)

[ routeコマンド ]

• routeコマンド

  routeコマンドにより、Windowsの経路情報の表示/追加/削除/変更/クリアなどの 操作が可能になります。

  routeコマンドを実行するには、MS-DOSプロンプト(command.com)が必要です。 例えば、「route print」と実行することにより、Windowsの保持している 経路(パケットの送信先のリスト)を表示することができます。

    C:\> route Manipulates network routing tables. ROUTE [-f] [command [destination] [MASK netmask] [gateway] [METRIC metric]] -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. command Must be one of four: PRINT Prints a route ADD Adds a route DELETE Deletes a route CHANGE Modifies an existing route destination Specifies the destination host. MASK Specifies that the next parameter is the 'netmask' value. netmask Specifies a subnet mask value to be associated with this route entry. If not specified, it defaults to 255.255.255.255. gateway Specifies gateway. METRIC Specifies that the next paramenter 'metric' is the cost for this 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, wildcards may be used for the destination and gateway, or the gateway argument may be omitted. 診断上の注意: (DEST & MASK) != DEST のとき、無効な MASK はエラーを発生します。 例> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1 The route addition failed: 87 例 : > route PRINT > route ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1 METRIC 3 ^destination ^mask ^gateway ^metric > route PRINT > route DELETE 157.0.0.0 > route PRINT

    C:\>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 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: > route PRINT > route ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1 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 > route PRINT 157* .... Only prints those matching 157* > route DELETE 157.0.0.0 > route PRINT C:\>
