We were planning to move to Active/Active setup from Active/Standby setup.
But as I read Active/Active is only supported in multiple context mode.
And VTI is supported in only Single context mode.
If this is true I will not be able to configure VTI in Active/Active setup, right?
Just make sure you are on 9.7 onward version of the ASA code. As VTI was introduce in 9.7 code here is the link in case you need it in regards to configurations
In addition to this, is it possible to configure two tunnels using different ISPs and keep them active? Please find the attachment for the reference. (Assume ASA1 is active firewall).
In that, I want to keep tunnel to 126.96.36.199 and 188.8.131.52 active.
