I have a CSS configured for web server failover.
We have two servers providing different fuctions that failover to backup servers at the DR site if one or the other server fails.
This is all working fine.
We want to add a second CSS at the DR site to provide access to our web servers if the Main site gets wiped out.
The DR site would also provide connectivty to the web servers if there is a loss of Internet connectivity at the main site.
How much configuration would be needed to my existing config to allow for this?
I would also have to configure the secondary CSS to be the failover unit.
Are there any examples on how to do this?

If there is a show tech I can't find it.
Anyway, I got confused there in my last post, you were answering my previous question.
Ok, so the Cisco guy's reply
"The preferlocal is for CSS to forward its local VIP for the relevant content rule."
-Yes, but not when doing zone based dns(I think)
"So when you configure preferlocal on primary CSS it replies with its own VIP, however DNS requests which are sent to Secondary CSS are not being sent to primary CSS. But instead secondary CSS replying with its own VIP? Is that correct?"
-Kind of. I don't think the preferlocal applies since this is zone based. The primary CSS round robins the response, 1,2,1,2,1,2. As does the secondary 1,2,1,2,1,2.
"Or does Secondary CSS once replies with primary CSS vip and next time with its own vip?"
-Yes. And to clarify this is with zone based dns with "dns-record a", not "add dns" under the content.
