Hi Lee Sutcliffe,

So the priority should avoid any problem with mixed LB?

    Could you clarify what you mean by mixed load balancing?

     

    Priority only ensures rules are executed in the preferred order.

      I run 2 scripts.

      Each script check LB to get the client IP match with a pool by subnet.

      So the 2 scripts are giving me the same results.

       

      I check for client IP.

      Script1:

      set strSelectedPool [class match -value [IP::client_addr] equals "MEM-Manager-Subnet-To-Pool-Pairs"]

      pool $strSelectedPool

      Scrip2:

      set strSelectedPool [class match -value [IP::client_addr] equals "ORG-Manager-Subnet-To-Pool-Pairs"]

      pool $strSelectedPool

       

      In that case when a request comes, it will mix the pools. and get the same result.

      You can’t have two ‘pool’ commands executing.

      You’ll need to add the following to stop iRule processing after the first pool has been selected (assuming an HTTP_REQUEST event

      event disbale HTTP_REQUEST

      What will happen to second pool in that case?
