How to Enable/Disable Express Route Peerings for DR Testing

One of my customers wanted to disable the Azure Express Route for their DR testing, I thought, this may be a very simple job to achieve by just deleting the Express Route private Peering and then re-create it later after the testing. But realized that it’s not that simple to do and also couldn’t find much info which confirms whether this is a right way or not. Unfortunately Azure portal doesn’t have Enable/Disable feature for Express Route peerings and it can only be disabled using the PowerShell cmdlets.

The overall time it took to Enable and Disable the private peering was less than 1 Minute. 

When a private peering is disabled, it will also change the state in the portal from Provisioned to Not Provisioned
