一台电脑两条线路一个电信IP一个联通的IP，解决访问电信的时候自动走电信线路，访问联通的时候自动走联通的线路，我们可以用到下面这个命令
  ROUTEDOS命令我们都可以在 Cmd 下用 route /? 来查看他的帮助信息
  先看一下他的帮助
  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 CHANGE 157.0.0.0 MASK 255.0.0.0 157.55.80.5 METRIC 2 IF 2
  CHANGE is used to modify gateway and/or metric only.
  ; route PRINT
  ; route DELETE 157.0.0.0
  ; route PRINT
  route - 显示 / 操作IP选路表
  总览 SYNOPSIS
  route [-CFvnee]
  route [-v] [-A family] add [-net|-host] target [netmask Nm] [gw Gw] [metric  N] [mss M] [window W] [irtt I][reject] [mod] [dyn] [reinstate] [[dev] If]
  route [-v] [-A family] del [-net|-host] target [gw Gw][netmask Nm] [metric  N] [[dev] If]
  route [-V] [--version] [-h] [--help]
  描述 DESCRIPTION
  route程序对内核的IP选路表进行操作。它主要用于通过已用ifconfig(8)程序配置好的接口来指定的主机或网络设置静态路由。
  选项 OPTIONS
  -v
  选用细节操作模式
  -A family
  用指定的地址族(如`inet'，`inet6')。
  -n
  以数字形式代替解释主机名形式来显示地址。此项对试图检测对域名服务器进行路由发生故障的原因非常有用。
  -e
  用netstat(8)的格式来显示选路表。-ee将产生包括选路表所有参数在内的大量信息。
  -net
  路由目标为网络。
  -host
  路由目标为主机。
  -F
  显示内核的FIB选路表。其格式可以用-e 和 -ee选项改变。
  -C
route add命令实例
  显示内核的路由缓存。
  del
  删除一条路由。
  add
  添加一条路由。
  target
  指定目标网络或主机。可以用点分十进制形式的IP地址或主机/网络名。
  netmask Nm
