As per the document in F5, the highest priority is preferred if there are atleast of 2 active pool members(highest priority) , when the count is less than 1, Ltm sends the traffic to the next higher priority pool members.

 

 

If there are only two pool members which will server the Virtual Server , will the below settings send the traffic to the second server if the primary server fails?

 

Server1 priority 2

 

server2 priority 1

 

 

Or I have to assign the servers two different pools and then use the below I rule to serve the purpose:

 

 

when LB_FAILED{

 

if { [active_members poolserver1] == 0 } {

 

pool poolserver2

 

}

 

}

Thanks,
