Netsh commands for routing IP

The following entries provide details for each command.

dump

Displays the routing IP context configuration of the remote access server in script form.

Syntax

dump

Remarks

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

Example

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

• From the command prompt:

  netsh routing ip dump > c:\test\routingipcfg.dmp

• From the netsh routing IP context prompt:

  set file open c:\test\routingipcfg.dmp

  dump

  set file close

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