[网络连接] 批处理提取ipconfig/all输出中的DHCP－IP作route命令的输入参数？

lrk

RT，我有多网卡，希望提取ipconfig /all输出中的其中一块网卡的DHCP服务器IP,作为route命令的输入参数，不知能否实现？

查了一下，发现一个贴的问题跟我的非常的相似：
[求助]用何命令获取PPPoE拨号连接的IP?
我的问题是这样：

对于如图的IP设置，我要提取后面一块网卡的DHCP的IP：10.104.176.145，作为route命令的参数：
route add 0.0.0.0 mask 0.0.0.0 10.104.176.145

因为这个值是会变化的，所以想做个批处理可以动态更新路由表。

参照找到那个帖子的，我写了下面的语句，可是却不成功，各位帮下忙了：

for /f "tokens=1,2* delims=:" %%i in ('ipconfig /all') do (
if /i "%%j"==" Netpas Win32 Virtual Network Adapter - Packet Scheduler Miniport" set flag=a
if defined flag (
if "%%i "==" DHCP Server . . . . . . . . . . . " route -p add 0.0.0.0 mask 0.0.0.0 %%j))
复制代码

for /f "tokens=1,2* delims=:" %%i in ('ipconfig /all^|find "IP Address"') do (
  set IP=%%j

route -p add 0.0.0.0 mask 0.0.0.0 %IP%

Batcher大：

非常多谢你的回复！我看了你的代码，觉得你理解错我的问题了，你的代码是把当前的IP地址作为后面命令的参数输入，是这样吧？我其实是想把DHCP服务器的IP作为参数输入。

我把“IP Address”改成“DHCP Server”，成功执行了。

不过有个小问题，就是我是双网卡的，刚好我的第一块网卡没有使用DHCP，上面没有错误。我想问一下，如果我的第一块网卡也使用了DHCP，那是不是没法选择那块网卡的DHCPIP了？

另外，我一楼改写的代码尝试去定位网卡再提取，可为什么不成功呢？还是批处理新手，希望解决这个问题学习下，呵呵！

第一块网卡的DHCP：

@echo off
for /f "tokens=1,2* delims=:" %%i in ('ipconfig /all^|find "DHCP Server"') do (
  set IP=%%j
  route -p add 0.0.0.0 mask 0.0.0.0 %IP%
  goto :eof
)
复制代码

最后一块网卡的DHCP：

@echo off
for /f "tokens=1,2* delims=:" %%i in ('ipconfig /all^|find "DHCP Server"') do (
  set IP=%%j
)
route -p add 0.0.0.0 mask 0.0.0.0 %IP%
