Netsh Routing IP IGMP Context Commands

dump

• You can dump the contents of the current configuration to a file that can be used to restore altered configuration settings.
  
  

The following commands save the current configuration as a script in the c:\test\igmpcfg.dmp file.

• From the command prompt:
  
  netsh routing ip igmp dump > c:\test\igmpcfg.dmp
  
  
• From the netsh routing ip igmp context prompt:
  
  set file open c:\test\igmpcfg.dmp
  
  dump
  
  set file close
  
  

You can use the netsh exec command to run the script created by the netsh dump command.
