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

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

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