Can anyone explain policy-based Cache Failover (CFO) in simple way as described in Advanced SLB Guide of ADX 12.1.00. Since the diagram and description does not seem to co-relate.
Also, can we use CFO when active-active redundancy is there?

CFO - This is used when the following are true;
1 The router sitting above the ServerIron has a policy/filter defined to send traffic to the ADX
2 Either the all cache servers are down or do not have the content requested
If NOT using CFO then if point 2 is true then the request would be dropped.
Hope that helps.
