LTM not packet loss deliver

Hello:

 

Just want to explore some options here..

 

LTM is doing load balancing for 3 servers, no persistency. Requirement is when LTM sent packet to a node, LTM requires packet response back, if at that time, there is a problem for the node down, Is that possible for LTM to send same packet to another node?

 

Thanks,

    I think in terms of having a Pool with 3 servers configured you are looking to set the "Action of Service Down" option from "None" to "Reselect"

     

    Reselect: Specifies that the system manages established client connections by moving them to an alternative pool member when monitors mark the original pool member down.

    Thanks jgranieri..

     

    that is possible option, but the problem is during monitor mark the original pool member down, it is still possible LB already sent a packet to that node.
