DESCRIPTION

The Get-NetRoute cmdlet gets IP route information from the IP routing table, including destination network prefixes, next hop IP addresses, and

route metrics. Run this cmdlet without any parameters to get all IP routes from the routing table. Specify parameters to narrow your results. For

instance, you can specify a particular interface or an IP address family.



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

-- IPv4

-- IPv6



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-AssociatedIPInterface [<CimInstance>]

-CimSession [<CimSession[]>]

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession

prefix contains an IP address prefix and a prefix length, separated by a slash (/). 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.



Required? false

Position? 1

Default value none

Accept pipeline input? false

-- Age. Publish and advertise IP route information with a finite valid lifetime in router advertisements.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-RouteMetric [<UInt16[]>]

Specifies an array of integer route metrics for IP routes. The cmdlet gets entries that have the metrics that you specify. To choose among

multiple routes, the computer adds this value to the interface metric value. The computer selects the route with the lowest combined value. To

modify the interface metric, use the Set-NetIPInterface cmdlet.

OUTPUTS

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.





Example 1: Get all routes



PS C:\\>Get-NetRoute | Format-List ????????Property *



This command gets all the routes for the computer, and then passes them to the Format-List cmdlet by using the pipeline operator. The Format-List

cmdlet displays all the properties of an object. For more information, type Get-Help Format-List.





Example 2: Get all IPv6 routes



PS C:\\>Get-NetRoute ????????AddressFamily IPv6



This command gets the routes that belong to the IPv6 address family.





Example 3: Get routes for a specified interface



PS C:\\>Get-NetRoute ????????InterfaceIndex 12



This command gets the IP routes associated with the interface that has an index of 12.





Example 4: Get the next hop for the default route



PS C:\\>Get-NetRoute ????????DestinationPrefix "0.0.0.0/0" | Select-Object ????????ExpandProperty "NextHop"



This command gets the next hop for the default route. The next hop gateway for the default route is also known as the default gateway. The command

gets the default IP routes, and passes them to the Select-Object cmdlet. That cmdlet displays the NextHop property for each default route. For

more information about displaying selected properties, type Get-Help Select-Object.





Example 5: Get IP routes to non-local destinations



PS C:\\>Get-NetRoute | Where-Object ????????FilterScript { $_.NextHop -Ne "::" } | Where-Object ????????FilterScript { $_.NextHop -Ne "0.0.0.0" } | Where-Object

????????FilterScript { ($_.NextHop.SubString(0,6) -Ne "fe80::") }



This command gets IP routes that have next hops that are not in the local subnet. The command gets all routes, and then passes them to a series of

Where-Object commands by using the pipeline operator. The command uses different filter scripts to discard routes that are the default gateway for

the two IP address families and the IPv6 addresses that begin with fe80. For more information about filtering by using Where-Object, type Get-Help

Where-Object.





Example 6: Get network adapters that have IP routes to non-local destinations



PS C:\\>Get-NetRoute | Where-Object ????????FilterScript {$_.NextHop -Ne "::"} | Where-Object ????????FilterScript { $_.NextHop -Ne "0.0.0.0" } | Where-Object

????????FilterScript { ($_.NextHop.SubString(0,6) -Ne "fe80::") } | Get-NetAdapter



This command gets network adapters that have IP routes that have next hops that are not in the local subnet. As in the previous example, the

command gets the routes that have next hop values by using the Get-NetRoute and the Where-Object cmdlets, and then passes those routes to the

Get-NetAdapter cmdlet by using the pipeline operator.





Example 7: Get IP routes that have an infinite valid lifetime



PS C:\\>Get-NetRoute | Where-Object ????????FilterScript { $_.ValidLifetime -Eq ([TimeSpan]::MaxValue) }



This command gets all IP routes, and then passes them to the Where-Object cmdlet by using the pipeline operator. The command selects those routes

that have a valid lifetime of the maximum value.
