Powershell Script Multiple Default Gateway

Posted by3 years ago

The PowerShell scripts let users perform the following operations: Retrieve the list of gateway clusters available for a user; Retrieve the list of gateway instances registered in a cluster, as well as their online or offline status; Modify the enable/disable status for a gateway instance within a cluster, as well as other gateway properties.

  • If you have multiple network adapters on your system, you can remove the function and simply enter the numerical value corresponding to the desired interface. If the command completes successfully, we should get the result as shown below: Now we have our IP Address, Subnet Mask and Default Gateway configured. However, one thing is missing.
  • I have forgotten to add the -defaultgateway parameter in the command. IP address was sucessfully assigned, but I cannot figure out a way to change/add a default gateway. Does anyone know how to do it via native powershell cmdlets (no gwmi, functions or scripts)?

Powershell script multiple default gateway windows 7

I have a VM deployment script that takes a -computername parameter and looks up the computername in DNS to get its IP address. I know that my default gateway always has the same first 3 octets as the IP address and then uses '.250' for the final octet. For example, if my IP address is 192.168.0.1, I need the default gateway to be 192.168.0.250. Right now my script uses a split and join method to create the default gateway, but I'm thinking this should be easy with regular expressions. What's the regular expression command in powershell that would take everything after the last '.' and replace it with '250'?

Gets the IP route information from the IP routing table.

Syntax

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 in the TechNet library.

Examples

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.

Example 2: Get all IPv6 routes

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

Example 3: Get routes for a specified interface

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

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

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

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

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.

Optional Parameters

  • IPv4
  • IPv6
Type:AddressFamily[]
Accepted values:IPv4, IPv6

Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type:SwitchParameter
Position:Named
Default value:None

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.

Type:CimInstance
Position:Named
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False

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 or Get-CimSession cmdlet.The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

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.

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

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.

Type:String[]
Position:0
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

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.
