Connection Mirroring across Cluster

Connection Mirroring is used to insure the session specific information remains consistent across an F5 pair (Active and Standby F5's).

 

 

Service Description:

 

Specifies that the system mirrors connections on each member of a redundant pair. Connection mirroring is the process of duplicating connections from the active system to the standby system. Enabling this setting ensures a higher level of connection reliability, but it may also have an impact on system performance.

 

 

An example of usage for this would be a shopping website to replicate the information to the Standby F5, just in case there was a failure on the Primary, the shopper would be able to keep all of the items in the shopping cart, rather than losing everything and having to start over (which they probably wouldn't and your company would lose money). You take a system hit for doing it, but it's the argument of "can we afford to do this" vs. "can we afford not to do this."

 

 

Hope this helps.

 

 

Depending on what you are looking at doing, you can look into Clone Pooling (its general use is to relay all traffic to an IDS System).
