Detaillierte Beschreibung

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 (https://technet.microsoft.com/library/bb727001.aspx) in the TechNet library.

Parameter

-AddressFamily<AddressFamily[]>

Specifies an IP address family. The cmdlet gets IP routes of the families that you specify. Die zulässigen Werte für diesen Parameter sind:

-- IPv4
-- IPv6

-AssociatedIPInterface<CimInstance>

Specifies an IP interface as a CIM object. The cmdlet gets IP routes that belong to the interface that you specify. To obtain an IP interface, use the Get-NetIPInterface cmdlet.

-CimSession<CimSession[]>

Das Cmdlet wird in einer Remotesitzung oder auf einem Remotecomputer ausgeführt. Geben Sie einen Computernamen oder ein Sitzungsobjekt ein, wie z. B. die Ausgabe eines New-CimSession oder Get-CimSession-Cmdlets. Der Standardwert ist die aktuelle Sitzung auf dem lokalen Computer.

-CompartmentId<UInt32[]>

Specifies an array of identifiers for network compartments in the protocol stack. By default, the cmdlet only gets Net routes in the default compartment. If you specify a value, the cmdlet gets any matching Net routes in all compartments in this field.

-DestinationPrefix<String[]>

Specifies an array of destination prefixes of IP routes. The cmdlet gets IP routes that use the prefixes that you specify. A destination 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.

-IncludeAllCompartments

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

-InterfaceAlias<String[]>

Specifies an array of aliases of network interfaces. The cmdlet gets IP routes for the interfaces that have the aliases that you specify.

-InterfaceIndex<UInt32[]>

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

-NextHop<String[]>

Specifies an array of next hop values. The cmdlet gets IP 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.

-PolicyStore<String>

Specifies a PolicyStore value. The cmdlet gets IP routes that have the PolicyStore value that you specify. Die zulässigen Werte für diesen Parameter sind:

-- 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.

-PreferredLifetime<TimeSpan[]>

Specifies an array of values for preferred lifetime, as TimeSpan objects, of IP routes. The cmdlet gets entries that have these values. To obtain a TimeSpan object, use the New-TimeSpan cmdlet. For more information, type Get-Help New-TimeSpan.

-Protocol<Protocol[]>

Specifies an array of types of routing protocols. The cmdlet gets entries that use the protocols that you specify. Die zulässigen Werte für diesen Parameter sind:

-- Bbn
-- Bgp
-- Dhcp
-- Dvmrp
-- Egp
-- Eigrp
-- EsIs
-- Ggp
-- Hello
-- Icmp
-- Idpr
-- Igrp
-- IsIs
-- Local
-- NetMgmt
-- Ospf
-- Rip
-- Rpl
-- Other

-Publish<Publish[]>

Specifies an array of publish settings of IP routes. The cmdlet gets entries that have the publish values that you specify. Die zulässigen Werte für diesen Parameter sind:

-- 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.

-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.

-ThrottleLimit<Int32>

Gibt die maximale Anzahl gleichzeitiger Vorgänge an, die zum Ausführen des Cmdlets hergestellt werden können. Wenn dieser Parameter ausgelassen wird oder der Wert 0 eingegeben wird, berechnet Windows PowerShell ® einen optimalen Drosselungsgrenzwert für das Cmdlet basierend auf der Anzahl der CIM-Cmdlets, die auf dem Computer ausgeführt werden. Der Grenzwert gilt nur für das aktuelle Cmdlet, nicht für die Sitzung oder den Computer.

-ValidLifetime<TimeSpan[]>

Specifies an array of values for valid lifetimes, as TimeSpan objects, for IP routes. The cmdlet gets entries that have the lifetimes that you specify. To obtain a TimeSpan object, use the New-Timespan cmdlet.

<CommonParameters>

Dieses Cmdlet unterstützt die allgemeinen Parameter: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer und -OutVariable. Weitere Informationen finden Sie unter about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Ausgaben

Der Ausgabetyp ist der Typ der Objekte, die vom Cmdlet ausgegeben werden.

  Das Microsoft.Management.Infrastructure.CimInstance-Objekt ist eine Wrapperklasse, die Windows-Verwaltungsinstrumentation-Objekte (Windows Management Instrumentation, WMI) angezeigt.

Beispiele

Example 1: Get all routes

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.

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

Example 2: Get all IPv6 routes

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

PS C:\> Get-NetRoute –AddressFamily IPv6

Example 3: Get routes for a specified interface

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

PS C:\> Get-NetRoute –InterfaceIndex 12

Example 4: Get the next hop for the default route

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.

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

Example 5: Get IP routes to non-local destinations

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.

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::") }

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

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.

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

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

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.

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