IAP-VPN failover to other IAP

hi all,

 

In instant IAP-VPN, we can have IPsec tunnel to main controller. If master IAP goes down and another IAP becomes master, will IPSec tunnel remains up or it will re-establish ?

 

If it re-establishes, is there anyway to minimize the downtime like having second IPSec tunnel from a backup IAP. So far in my research i am almost sure that there is no concept of backup IAP, but please correct me if i am wrong.

Yes it will re-establish. If you have a second controller, you can create a backup IPSec to that controller.

Hi,

I don't have the second controller but please also elaborate on other points like is there a possibility of having a backup IAP to minimize the downtime ?

If not, how much time does it takes to re-establish ? also is it a good design ?

Best Regards

It takes a few seconds. Most users won't even notice.
