Hello, No, the connections are not mirrored ! To share in case it might help someone someday: I had a TG conf problem, the VS was configured in the TG1 and nexthop (floating self-ip) in the TG2, I configured everything in TG1, and it works. Thank you Mohamed_Ahmed_KansohM_Saeed
It consume Bigip resources specially in heavy environments.
Let we imagine you have 100K connections in Active unit connection table , you see that as 100K connections only but at the same time Active unit handles 200K Connections because it processes 100K and move/mirror the same 100 K connections to the other unit.
Imagine you have a virtual server receive 1 or 2 millions of traffic and so on this of course will impact you and degrade sys performance.
Mirror Active connections is not an easy task like triggering failover or even doing incremental config sync.
You need a robust connectivity between HA pairs also I prefare to use a back to back connectivity for that
