Hi Albert,

 

as I said, the "match across pools" option is not needed for failovers to a different pool member of the same pool.

 

Also keep in mind that the failover capabilities of a LTM is just HTTP-based and does only work seemlessly, if your web application could handle non-sticky sessions. If your web application can't handle the load shift from the failed node to its standby system, then you have to implement a Single-Sign-On mechanism either on your web application itself or by using some sort of pre-authentication and single-sign-on functionalities by using APM or plain iRules.

 

Cheers, Kai
