Detailed Description

The Remove-NetRoute cmdlet removes IP routes from the IP routing table. Run this cmdlet without any parameters to remove all IP routes from the routing table, including default routes. You can also specify routes to remove by specifying parameters, or by using the Get-NetRoute cmdlet.

For more information about routing, see Chapter 5 - IP Routing (http://technet.microsoft.com/library/bb727001.aspx) in the TechNet library.

Parameters

-AddressFamily<AddressFamily[]>

Specifies an array of IP address families of IP routes. The cmdlet removes IP routes that belong to the families that you specify. The acceptable values for this parameter are: 

-- IPv4
-- IPv6

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • Microsoft.Management.Infrastructure.CimInstance#rootStandardCimv2MSFT_NetRoute

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.


Outputs

The output type is the type of the objects that the cmdlet emits.

  • None

Examples

Example 1: Remove all routes

This command removes all of the IP routes on the computer, including default routes.


PS C:\> Remove-NetRoute

Example 2: Remove routes for a specified next hop
