Limit in traffic group in BIG IP LTM

Ok, I can't see any reasons for F5 to limit the amount of traffic groups. You can most likely continue with your thing. Although from a design perspective I'd generally not recommend it as it becomes a bit harder to troubleshoot (especially considering that you don't even use active active). In regards to active/active, in case you would use it for the performance, which essentially in manycases would mean that one load balancer is not enough a hardware failure could bring the whole house down (unless you have an additional stand by device in the cluster as well). Just my two cents. /Patrik
