Why each option
Connection mirroring, which ensures that active connections persist after a failover, is configured as an optional feature on a per-virtual server basis.
TCP profiles define connection properties but do not directly configure connection mirroring; mirroring is a virtual server property.
Pools group members and define load balancing, but connection mirroring is not configured at the pool level; it is a virtual server attribute.
Connection mirroring is an optional feature that must be explicitly enabled per virtual server and is not a default behavior on BIG-IP systems.
Connection mirroring is enabled or disabled as an option within the configuration of a virtual server. When enabled for a virtual server, it ensures that connection state information is synchronized with the peer device, allowing active connections to persist through a failover event.
