preempt for priority group

one virtual server, one pool, two servers. all traffic goes to 01server until it's down. i suppose priority group should be used. my question is when 01 is down, all traffic goes to 02. when 01 comes back, 1. will all traffic goes to 01? 2. if 1. is true, can i make all traffic remains to 02? 3. if 2 can be done, how can i use 01 server again?

 

thanks

    Hi,

     

    when 01 comes back:

     

    • all existing TCP connections remains on 02
    • New TCP connections are balanced according to the policy
      • if persistence is not set, New TCP connections go to 01
      • if persistence is set, persistence records will override pool priority group, New TCP connections without persistence record go to 01
