        if {[LB::status pool xyz_pool member x.x.x.x 7011] equals "up"} {
            node x.x.x.x 7011
        }
        elseif {[LB::status pool xyz_pool member y.y.y.y 7011] equals "up"} {
            node y.y.y.y 7011

            if {[LB::status pool xyz_pool member y.y.y.y 7012] equals "up"} {
            node y.y.y.y 7012
            }
            elseif {[LB::status pool xyz_pool member x.x.x.x 7012] equals "up"} {
            node x.x.x.x 7012
        }
    }
}


x.x.x.x - app1
y.y.y.y - app2

Hi Babu, Thanks for this Irule. I have two different Virtual server 1) VS_7011 2) VS_7012. So i planning to create two different irule and bind it with respective virtual server. IRULE 1 when LB_SELECTED { if {[LB::status pool xyz_pool member x.x.x.x 7011] equals "up"} { node x.x.x.x 7011 } elseif {[LB::status pool xyz_pool member y.y.y.y 7011] equals "up"} { node y.y.y.y 7011 } IRULE2 when LB_SELECTED { if {[LB::status pool xyz_pool member x.x.x.x 7012] equals "up"} { node x.x.x.x 7012 } elseif {[LB::status pool xyz_pool member y.y.y.y 7012] equals "up"} { node y.y.y.y 7012 }
