篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在Azure上通过Powershell创建多Interface的Cisco CSR路由器相关的知识，希望对你有一定的参考价值。

前面通过Json的Template在Azure上创建了Cisco的CSR路由器。但那个Json的template只支持1块网卡。如果需要多网卡的Cisco CSR路由器，可以改上篇文章中提到的Json Template文件，也可以用Powershell的脚本创建。

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

)
