在 Azure 上通过 Powershell 创建多 Interface 的 Cisco CSR 路由器

魏衡，微软云资深架构师，国内 Azure 最早的架构师之一。

本文将介绍如何用 Powershell 创建多 Interface 的 Cisco CSR 路由器

一、确定Cisco CSR Image的位置

和上篇文章相同，Cisco CSR Image的链接如下，我把这个文件public出来了，大家可以直接下载：

https://ciscorouter.blob.core.chinacloudapi.cn/image/CSR_3_16_4aS_CCO.vhd

二、编写Powershell脚本，创建2网卡的Cisco CSR路由器

function new-ciscocsr{
param(
#The VM resource group
[Parameter(Mandatory=$true)]
[String]$rgname,

#The VM name
[Parameter(Mandatory=$true)]
[String]$vmname,

#The High Avalibility Set name
[Parameter(Mandatory=$true)]
[String]$hasetname,

#The new VM IP name
[Parameter(Mandatory=$true)]
[String]$vmpipname,

#The Vnet Name
[Parameter(Mandatory=$true)]
[String]$vnetname,

#The Subnet1 Name
[Parameter(Mandatory=$true)]
[String]$subnetname1,

#The Subnet2 Name
[Parameter(Mandatory=$true)]
[String]$subnetname2,

#The new VM size
[Parameter(Mandatory=$true)]
[String]$vmsize,

#The new user
[Parameter(Mandatory=$true)]
[String]$newuser,

#The new password
[Parameter(Mandatory=$true)]
[String]$newpwd,

#The Image URL
[Parameter(Mandatory=$true)]
[String]$ImageURL
)

#Get a random text as the random text
$hash = $null
for ($i = 0; $i -le 4; $i++){
$j = (97..122) | Get-Random -Count 1 | % {[char]$_}
$hash = $hash + $j
}
for ($i = 0; $i -le 4; $i++){

$hash = $hash + $j
}

三、登录路由器
