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 in the TechNet library.

Examples

Example 1: Remove all routes

PS C:\>Remove-NetRoute

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

Example 2: Remove routes for a specified next hop

PS C:\>Remove-NetRoute -NextHop "192.168.0.1"

This command removes all of the IP routes that have a next hop of 192.168.0.1.

Type:	String[]
Position:	0
Default value:	None
Required:	False

Accept wildcard characters:	False

-IncludeAllCompartments

Indicates that the cmdlet includes routes from all configured network compartments. If you do not specify this parameter, the cmdlet removes only routes in the default network compartment.

Specifies an array of indexes of network interfaces. The cmdlet removes IP routes for the interfaces located at the indexes that you specify.

Type:	UInt32[]
Aliases:	ifIndex
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-InterfaceMetric

Specifies an array of integer interface metrics for network interfaces. The cmdlet gets IP routes for the interfaces that have the metric that you specify.

Type:	UInt32[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-NextHop

Specifies an array of next hop values. The cmdlet removes routes that have the next hop values that you specify. A value of 0.0.0.0 for IPv4 or :: for IPv6 indicates that the route is on the local subnet.

Type:	String[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PolicyStore

Specifies a PolicyStore value. The cmdlet removes IP routes that have the PolicyStore value that you specify. The acceptable values for this parameter are:

• ActiveStore. The IP address information is valid.
• PersistentStore. The computer saves IP address information across restarts. When the computer restarts, it copies the saved settings to the ActiveStore.
