Parameter Set: ByInterfaceIndex
New-NetRoute [-DestinationPrefix] <String> -InterfaceIndex <UInt32> [-AddressFamily <AddressFamily> ] [-AsJob] [-CimSession <CimSession[]> ] [-NextHop <String> ] [-PolicyStore <String> ] [-PreferredLifetime <TimeSpan> ] [-Protocol <Protocol> ] [-Publish <Publish> ] [-RouteMetric <UInt16> ] [-ThrottleLimit <Int32> ] [-ValidLifetime <TimeSpan> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The New-NetRoute cmdlet creates an IP route in the IP routing table. Specify the destination prefix, and specify an interface by using the interface alias or the interface index.

IP routing is the process of forwarding a packet based on the destination IP address. Routing occurs at TCP/IP hosts and at IP routers. The sending host or router determines where to forward the packet. To determine where to forward a packet, the host or router consults a routing table that is stored in memory. When TCP/IP starts, it creates entries in the routing table. You can add entries either manually or automatically.

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 the IP address family. The cmdlet uses the family that you specify for the IP route. The acceptable values for this parameter are: 

-- IPv4
-- IPv6

If you do not specify this parameter, the cmdlet selects a value based on the other input that you provide.

-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.

A value of 0.0.0.0/0 for IPv4 or ::/0 for IPv6 indicates that the value of the NextHop parameter is a default gateway. The prefix length of the local host must match the prefix specified in this parameter, with all remaining address fields set to zero.

-NextHop<String>

Specifies the next hop for the IP route. The cmdlet assigns the next hop that you specify to the IP route. A value of 0.0.0.0 for IPv4 or :: for IPv6 indicates that the route is on the local subnet.

-PolicyStore<String>

Specifies the PolicyStore value. The cmdlet assigns the PolicyStore value that you specify to the IP route. 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.

The default value is ActiveStore. Specify ActiveStore only.

If you do not specify this parameter, the default entries are created in both the ActiveStore and the PersistentStore.

-PreferredLifetime<TimeSpan>

Specifies a preferred lifetime, as a TimeSpan object, of an IP route.The cmdlet assigns the lifetime that you specify to the IP route. To obtain a TimeSpan object, use the New-Timespan cmdlet. For more information, type Get-Help New-TimeSpan. The default value for a lifetime is infinite.

-Protocol<Protocol>

Specifies the type of routing protocol. The cmdlet assigns the protocol that you specify to the IP route. The acceptable values for this parameter are: 

-- Bbn
-- Bgp
-- Dhcp
-- Dvmrp
-- Egp
-- Eigrp
-- EsIs
-- Ggp
-- Hello
-- Icmp
-- Idpr

-Publish<Publish>

Specifies the publish setting of an IP route. The cmdlet assigns the publish setting that you specify to the IP route. The acceptable values for this parameter are: 

-- No. Do not publish or advertise IP route information in router advertisements.
-- Yes. Publish and advertise IP route information with an infinite valid lifetime in router advertisements.
-- Age. Publish and advertise IP route information with a finite valid lifetime in router advertisements. Specify a valid lifetime by using the ValidLifetime parameter.

The default value is No.

-RouteMetric<UInt16>

Specifies an integer route metric for an IP route. The cmdlet assigns the metric that you specify to the IP route. The default value is 256. To choose among multiple routes, the computer adds this value. The computer selects the route with the lowest combined value. To modify the interface metric, use the Set-NetIPInterface cmdlet.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

<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.

  • None

Outputs

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

  • Microsoft.Management.Infrastructure.CimInstance#root\StandardCimv2\MSFT_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.


Examples

Example 1: Add an IP route to the routing table

This example adds a routing table entry, and then displays the properties of all the entries in the routing table.

The first command creates a route for the destination prefix 10.0.0.0/24 for the interface that has the index of 12. The command specifies 192.168.0.1 as the next hop.

The second command uses the Get-NetRoute cmdlet to get all the routes for the computer, and then passes them to the Format-List cmdlet by using the pipeline operator. The Format-List cmdlet can display all the properties of an object. For more information, type Get-Help Format-List.


PS C:\> New-NetRoute –DestinationPrefix "10.0.0.0/24" –InterfaceIndex 12 –NextHop 192.168.0.1
PS C:\> Get-NetRoute | Format-List -Property *
