Manipulates network routing tables.
ROUTE [-f] [-p] [-4|-6] command [destination]
                  [MASK netmask]  [gateway] [METRIC metric]  [IF interface]
  -f           Clears the routing tables of all gateway entries.  If this is
               used in conjunction with one of the commands, the tables are
               cleared prior to running the command.
  -p           When used with the ADD command, makes a route persistent across
               boots of the system. By default, routes are not preserved
               when the system is restarted. Ignored for all other commands,
               which always affect the appropriate persistent routes. This
               option is not supported in Windows 95.
  -4           Force using IPv4.
  -6           Force using IPv6.

Thanks for the reply it worked with little modification i specified CSV path directly instead of using split
i have few question what is the use of split-path and $pscommandoath parameter why do we use args [0].once again thanks for the help
below is the script
$FileData = Import-Csv -Path excel.csv
$Object = @()
Foreach ($Entry in $FileData) {
$Object += New-Object PSObject -Property @{
Name = $Entry.Name
Gateway = $Entry.DefaultipGateway
Foreach ($Obj in $Object) {
Invoke-Command -ComputerName $Obj.Name -ScriptBlock {
Write-Output -Verbose $env:COMPUTERNAME
Write-Output -Verbose $args[0]
#route add -p 25.175.0.0 mask 255.246.0.0 $args[0]
#route print
} -ArgumentList $Obj.Gateway
