Active/Standby loadbalancing

Hi bigbrother,

 

 

Priority group activation will work with two pool members. You don't need to use ratio though for this scenario. If you define one member at a higher priority with priority group activation set to 1 then the higher priority pool member will receive all traffic. If it goes down, then all traffic will be sent to the lower priority member. When the higher priority pool member comes back up, all new connections will do to it. Persistence should ensure that existing sessions would be sent to the previously selected member.

 

 

If you want clients to stick to the second pool member even after the first one comes back up, you can use a simple iRule to do this:
